1. Right Side Blue, Left Side True
[Verse 1]
Follow the tide where the vena cava spills,
superior, inferior, two rivers off the hills,
into the right atrium, a dim and unlit room,
blood the color of midnight, hauling carbon's fume.
Tricuspid swings open, three flaps like a fan,
feeds the right ventricle, the engine's second hand,
pulmonic valve exhales it, sends it up and away,
through the pulmonary artery, the one vessel painted gray.
[Chorus]
Right side blue, left side true,
tricuspid, pulmonic, that's the right side's cue,
mitral, aortic, on the left we flow,
deoxygenated enters, oxygenated go.
Trace the loop, don't drop the thread,
blue goes out and comes back red,
four rooms, four doors, one steady beat,
structure by structure, the circuit's complete.
[Verse 2]
Lungs hand it back through four pulmonary veins,
oxygen riding shotgun, rinsing out the stains,
left atrium receives it, the calmest of the four,
mitral valve, two leaflets, closing like a bicuspid door.
Left ventricle flexes, the thickest wall in town,
built to shove a body's worth of pressure around,
aortic valve springs open, semilunar and precise,
out through the aorta — the artery of highest price.
[Verse 3]
Now follow the spark, not the crimson tide,
sinoatrial node, the pacemaker, sits high on the right side,
sixty to a hundred, it's whispering the beat,
down to the AV node, taking a purposeful retreat,
a pause that lets the atria empty out their share,
then the Bundle of His splits — a left lane and a right,
Purkinje fibers scatter like roots beneath the floor,
squeezing ventricles skyward, that's the systole roar.
Septum stands the border between the blue and red,
coronary arteries crown the muscle, keep it fed,
pericardium's the coat, myocardium's the might,
endocardium's the lining, smooth and satin-tight.
[Bridge]
This isn't memorized, it's mapped and understood,
connection to connection, the way the current should —
chamber feeds a valve, a valve feeds an artery's line,
learn the wiring once and the whole thing stays online.
[Verse 4]
Every heartbeat's a lesson, a loop you can retrace,
map the chambers, valves, and vessels, give the current its place,
from vena cava's whisper to aorta's mighty shout,
the body's story circulates, and never runs out,
diastole fills the chambers, systole sends the wave,
this rhythm keeps repeating from the cradle to the grave.
[Chorus]
Right side blue, left side true,
tricuspid, pulmonic, that's the right side's cue,
mitral, aortic, on the left we flow,
deoxygenated enters, oxygenated go.
Trace the loop, don't drop the thread,
blue goes out and comes back red,
four rooms, four doors, one steady beat,
structure by structure, the circuit's complete.
[Outro]
Sinoatrial whispers, the Bundle carries on,
vena cava to aorta, gone before the dawn —
say it slow, structure by structure, till the whole map wakes.
2. Sip Slow, Slam Hard
[Verse 1]
Right atrium first, the thin-walled receiving hall,
Superior vena cava drops its cargo, hears the call,
Inferior vena cava joins, coronary sinus too,
Three rivers pouring inward, one chamber pulling through,
Walls are paper-soft, a low-pressure gentle guest,
Tricuspid swings the door and sends it toward the chest.
[Chorus]
Right side sips it slow, left side slams it hard,
Vena cavas feed the top, aorta guards the yard,
Tricuspid, pulmonary, mitral, aortic gate,
Four valves keep the traffic moving, nothing hesitates,
RA to RV, LA to LV, the pattern never bends,
Follow the four small rooms till the circuit never ends.
[Verse 2]
Right ventricle's a crescent, moon-shaped and rough inside,
Coarse trabeculations ridge the walls like canyon tide,
Only three to five millimeters, thin but built for speed,
Short hop to the lungs is all this pump chamber's gonna need,
Pulmonary valve swings open, sends the blood out west,
Toward the lungs for oxygen, that's the low-pressure quest.
[Verse 3]
Left atrium sits posterior, quiet behind the scene,
Four pulmonary veins return what the lungs made clean,
Oxygen-rich cargo drifting back from the exchange,
Mitral valve's the gateway to the chamber built for range,
Left ventricle waits conical, sculpted like a horn,
Eight to twelve millimeters thick, the apex here is born.
[Chorus]
Right side sips it slow, left side slams it hard,
Vena cavas feed the top, aorta guards the yard,
Tricuspid, pulmonary, mitral, aortic gate,
Four valves keep the traffic moving, nothing hesitates,
RA to RV, LA to LV, the pattern never bends,
Follow the four small rooms till the circuit never ends.
[Verse 4]
Aortic valve's the exit, the biggest push it's got,
Blood shoots to the body, every organ, every plot,
Right ventricle's a rowboat, left's an ocean liner, hear?
Pulmonary trip is short, systemic trip's the wary,
Thin walls handle local runs, thick walls handle far,
That's why the left ventricle's the sturdiest little star.
[Verse 5]
Sinoatrial node ignites the spark up in the right,
AV node catches, holds it, then releases it to flight,
Bundle branches carry current down the septal wall,
Purkinje fibers scatter it, and that's the final call,
Systole and diastole, the squeeze and then the rest,
Every heartbeat is this circuit passing every test.
[Bridge]
Superior, inferior, sinus—three feed the right,
Four veins whisper to the left, that's the atrium's delight,
Tricuspid, mitral, inlet valves that guide the tide,
Pulmonary, aortic, outlets standing side by side,
Say it soft now: thin then thick, short then far,
That's the whole heart's story in a four-room bar.
[Outro]
Four rooms, one rhythm, the whole map makes sense,
Thin to thick, right to left, the heart's own residence.
3. Fossa Ovalis, Door in the Wall
[Verse 1]
Fossa ovalis, a dimple, a scar,
where the foramen ovale left its mark on the wall
Interatrial septum, splittin' RA from LA,
open before birth — that's the fetal blueprint, okay
Blood skips the lungs, takes the shortcut through the door,
seals itself shut once you're breathing, that's the law
But leave a little gap and you call it a PFO,
bigger hole stays open — ASD, now you know
[Chorus]
Septa, стена, la pared que separa,
walls in the heart, manteniendo el compás
Fossa ovalis, дырка that was meant to close,
listen close, mi amor, that's the way the story goes
Septum muscular, septum membranoso too,
every wall's got a job — la sangre sabe qué hacer
[Verse 2]
Now drop down south to the ventricles, my friend,
interventricular septum, thick wall without end
Muscular part is the meat, the brawny底 — I mean base,
built like a boxer's jaw, holdin' up the space
But up top by the valves it goes thin and refined,
membranous, outlet, infundibular — same design
Remember this patch, this fibrous little strip,
truncus arteriosus starts right here — don't let it slip
[Chorus]
Septa, стена, la pared que separa,
walls in the heart, manteniendo el compás
Fossa ovalis, дырка that was meant to close,
listen close, mi amor, that's the way the story goes
Septum muscular, septum membranoso too,
every wall's got a job — la sangre sabe qué hacer
[Verse 3]
Small piece left, where the crossroads convene,
atrioventricular septum, quiet and lean
Atrial wall shakes hands with the ventricular side,
right where the AV node and bundle reside
Surgeon's needle passes close, gotta thread it right,
one wrong stitch and you've blocked the electric light —
heart block waitin' in the shadow of that seam,
respect the geography, protect the conduction stream
[Verse 4]
Ostium primum, ostium secundum, learn the two,
septum primum drops down first, secundum follows through
Overlap and fuse, the foramen seals up tight,
fail that fusion young, the shunt stays open, day and night
Endocardial cushions rise to close the middle gate,
miss that fusion point and you've built an AV defect's fate
[Bridge]
Три перегородки, tres paredes en total,
each one a border, each one a protocol
IAS, IVS, and the AV in between,
learn the map of the wall and you'll read the machine
No es solo anatomía, it's the wiring underneath,
guard the membranous patch — Lesson Three's waitin' beneath
[Chorus]
Septa, стена, la pared que separa,
walls in the heart, manteniendo el compás
Fossa ovalis, дырка that was meant to close,
listen close, mi amor, that's the way the story goes
Septum muscular, septum membranoso too,
every wall's got a job — la sangre sabe qué hacer
[Outro]
Fossa ovalis... sealed but remembered,
membranous septum... thin but essential,
AV crossing... handle with care —
the walls tell the story, if you know where to stare
4. Vein to Artery, Mirror the Beat
[Verse 1]
Vein to atrium, that's the entry gate,
blood comes home tired, low pressure, no debate.
Right side whispers: tricuspid, swing the door,
into the ventricle, muscle on the floor.
Pulmonary valve cracks open, quick and clean,
off to the lungs through that arterial ravine.
Vein—atrium—valve—ventricle—valve—artery,
memorize the order, it's cardiac artistry.
[Chorus]
Veia, átrio, valva, ventrículo, valva, artéria—
essa é a ordem, essa é a matéria.
Twice through the heart, mirror on the right,
same six steps dressed in different light.
Vein to artery, never skip a stair,
cada batida canta essa oração.
[Verse 2]
Now cross the septum, walk the other side,
pulmonary veins bring oxygen like a tide.
Left atrium catches it, calm and full,
mitral valve opens, gentle, never dull.
Left ventricle flexes, the strongest room in town,
aortic valve springs the whole body's crown.
Same six steps, just wearing a different name—
vein, atrium, valve, ventricle, valve, artery, same game.
[Chorus]
Veia, átrio, valva, ventrículo, valva, artéria—
essa é a ordem, essa é a matéria.
Twice through the heart, mirror on the right,
same six steps dressed in different light.
Vein to artery, never skip a stair,
cada batida canta essa oração.
[Verse 3]
Now snap the chain and see what forms—
a missing link, anatomy performs.
Tricuspid atresia—that door's sealed shut,
transposition swaps the arteries, crosses the route.
Double outlet—two roads leaving one room,
truncus arteriosus, one trunk where there's usually two.
Every defect's just the pattern gone wrong,
broken, missing, or doubled somewhere along the song.
[Bridge]
(Female) Elo quebrado, elo que sobrou—
(Male) name the missing step, and the diagnosis is yours.
Six links only, count them like a rosary,
find the fault, you've found the anomaly.
(Female) Não é mágica, é geometria—
trace the pipeline, read the anatomy.
[Verse 4]
So trace it twice, right lung side then the left,
vein through atrium, valve, chamber, valve, then the exit.
Deoxygenated rides the tricuspid car,
oxygen-rich takes the mitral, riding far.
Learn the sequence, hold it steady in your mind,
every twisted heart's this same chain, redefined.
[Chorus]
Veia, átrio, valva, ventrículo, valva, artéria—
essa é a ordem, essa é a matéria.
Twice through the heart, mirror on the right,
same six steps dressed in different light.
Vein to artery, never skip a stair,
cada batida canta essa oração.
[Outro]
(Female) Vein... atrium... valve... ventricle... valve... artery.
(Male) Twice through the chest, essa é a anatomia.
Six links, two sides, one steady heart—
break one down and you'll name the part.
5. Right Side, Left Side, One Heartbeat
[Verse 1]
Top right box, that's the right atrium, first stop,
Vena cava pours in, superior and inferior drop,
Through the tricuspid — three flaps swingin' like a door,
Into right ventricle, thick wall, ready for the chore,
Pulmonic valve kicks open, pulmonary artery's the lane,
Blood ships off to lungs, trade the carbon for the gain,
Write it, right it, label every twist and bend,
Vena cava, atrium, valve, ventricle, valve again.
[Chorus]
Право, лево — две дороги, one машина,
Right side, left side, that's the cardiac scene,
Vena cava to aorta, круг за кругом clean,
Label it, build it, повтори — you know the routine.
[Verse 2]
Now the left side, mirror image, different job,
Four pulmonary veins deliver, oxygen-fat, no sob,
Left atrium fills up, pushes through the mitral gate,
Two flaps only, bicuspid, keepin' the flow straight,
Left ventricle's the powerhouse, wall thick as a fist,
Aortic valve springs open, don't you dare resist,
Aorta arches up and out, the body's superhighway,
Systemic circuit runnin', that's the left side's byway.
[Chorus]
Право, лево — две дороги, one машина,
Right side, left side, that's the cardiac scene,
Vena cava to aorta, круг за кругом clean,
Label it, build it, повтори — you know the routine.
[Bridge]
Take the clay, roll it thin, shape a rubbery hose,
Red for the aorta, blue for the vein that flows,
Set 'em side by side — two loops, not competin', collaboratin',
Pulmonary circuit left, systemic on the right, no debatin'.
Where the foam tubes kiss and fuse into one seam,
That's anastomosis — vessels joined, a single stream,
Small word, big meaning: connection point, no gap,
Press it, mold it, now you're holdin' the whole map.
[Verse 3]
Quiz yourself, cover the labels, only chambers stare,
Can you chant the chain from cava to the aortic pair?
Right: cava, atrium, tricuspid, ventricle, pulmonic, lung,
Left: vein, atrium, mitral, ventricle, aortic, done and sung,
Advanced learner, don't just memorize the name,
Trace the current, feel the pressure, understand the game,
Septum in the middle keeps the two lanes separate and true,
No mixing, no merging — one heart, two jobs to do.
[Chorus]
Право, лево — две дороги, one машина,
Right side, left side, that's the cardiac scene,
Vena cava to aorta, круг за кругом clean,
Label it, build it, повтори — you know the routine.
[Outro]
Clay in your fingers, chart under your pen,
Say the chain again, and again, and again,
Два круга, одно сердце — that's the lesson today,
Right, left, valve to vessel — now go label it away.
6. No Backflow, No Boom
[Verse 1]
Right atrium loads, tricuspid's the gate,
Three flaps of tissue holding steady weight,
Ventricle relaxes, diastole's the cue,
Flaps swing open wide, blood comes pouring through,
Squeeze comes next, systole tightens the room,
Three leaflets slam shut, no backflow, no boom,
Chordae tendineae anchor every hinge,
One-way door, no reverse, no fringe.
[Chorus]
Tri, pulmo, mitral, aortic — count the four,
Blood walks forward, never through the back door,
Three and three then two and three, that's the leaflet code,
Doors that open once and shut — that's the one-way road.
[Verse 2]
Right ventricle's loaded, now it's pushing time,
Pulmonary valve's semilunar, moon-shaped design,
Three cusps like parachutes catching the tide,
Systole fires, they flatten and slide,
Lungs get the blood, oxygen's the goal,
Diastole comes, cusps snap and control,
No backflow to the chamber, the pressure holds true,
Semilunar sentry standing guard for you.
[Chorus]
Tri, pulmo, mitral, aortic — count the four,
Blood walks forward, never through the back door,
Three and three then two and three, that's the leaflet code,
Doors that open once and shut — that's the one-way road.
[Verse 3]
Cross to the left side, mitral's the name,
Two leaflets only, a bishop's hat's the claim,
Atrium fills, the ventricle takes a rest,
Diastole opens the double-flap chest,
Then the squeeze — aortic valve takes the call,
Three semilunar cusps guard the great wall,
Systole blasts blood out to the aorta's bend,
Backflow to the ventricle? Not on my watch, friend.
[Verse 4]
Stenosis stiffens, the doorway grows tight,
Blood fights the leaflets, squeezing through fright,
Regurgitation's the leak when the seal fails,
Backflow sneaks past, the pressure derails,
Murmurs sing out when the flow turns rough,
Doctors listen close, the heartbeat's the proof,
Four valves, one rhythm, keep the blood in line,
Guard the gates well, and the heart runs fine.
[Bridge]
Now picture the split that never occurred,
Pulmonary and aortic, one root, one word,
Truncus arteriosus — the valves never divide,
A single truncal valve, nothing to separate the tide,
Semilunar cousins fused into one seam,
An embryo's mistake writes a different scheme,
Two vessels reduced to a single doorway wide,
One valve, one truncus, no room to divide.
[Chorus]
Tri, pulmo, mitral, aortic — count the four,
Blood walks forward, never through the back door,
Three and three then two and three, that's the leaflet code,
Doors that open once and shut — that's the one-way road.
[Outro]
Tricuspid, pulmonary, mitral, aortic — recite the score,
Three-three-two-three, the leaflets keep the score,
Every valve a one-way door, forward is the law,
Backflow's forbidden — that's the final draw.
7. Wishbone Split, One Root Remains
[Verse 1]
Right ventricle fires it, out through the front door,
Pulmonary artery leaning left, low to the floor,
One trunk, main pulmonary — the common stem,
Its presence or absence writes the truncus problem.
Splits like a wishbone, RPA slides back,
Tucks behind the aorta on its right-lung track,
LPA keeps rolling, straight shot to the left,
Two branches, one root — that's the vessel's whole self.
[Verse 2]
Left ventricle's engine, posterior, tucked right,
Aorta rises behind while the PA holds the front light,
Ascending aorta, sinuses of Valsalva bloom,
Left and right coronaries branch out of that room.
Arch swings over — normally hooks the left bronchus,
Innominate first, then carotid, then subclavian — watch us,
Flip the arch right-sided, mirror the same three,
Brachiocephalic, carotid, subclavian — see?
[Chorus]
Спираль, spiral, twisting like a vine,
Aorta behind, pulmonary in front — that's the design,
Coração puxa sangue, heart pulls the blood through,
PA e aorta dançam — dancing two by two,
Спираль вокруг сердца — spiral round the core,
Two great vessels crossing, that's the truncus lore.
[Verse 3]
Watch the choreography, this ain't random chance,
Aorticopulmonary septum spins its spiral dance,
PA starts up front, ends posterior-high,
Aorta starts behind then arches through the sky.
When that septum never forms, no spiral gets to grow,
But branch arteries on the trunk still echo what they know,
Type two truncus keeps that ghost-twist in the chest,
The spiral course remembers even when the wall's undressed.
[Chorus]
Спираль, spiral, twisting like a vine,
Aorta behind, pulmonary in front — that's the design,
Coração puxa sangue, heart pulls the blood through,
PA e aorta dançam — dancing two by two,
Спираль вокруг сердца — spiral round the core,
Two great vessels crossing, that's the truncus lore.
[Verse 4]
Superior, inferior vena cava feed the right,
Coronary sinus joins them — the heart's own drainage site,
Four pulmonary veins pour into the left,
Oxygen cargo home from the lung's own theft.
Ductus arteriosus, fetal bridge PA to aorta,
Closes after birth like a door that no longer supports ya,
Persistent or absent — matters in the CHD chart,
Often missing in truncus — memorize that part.
[Bridge]
Труба direita, труба левая — right pipe, left pipe spun,
Every vessel's got a partner, every artery's got a son,
Sinuses de Valsalva, coronárias saem lá,
Spiral, спираль — the fingerprint of how the heart was made.
[Chorus]
Спираль, spiral, twisting like a vine,
Aorta behind, pulmonary in front — that's the design,
Coração puxa sangue, heart pulls the blood through,
PA e aorta dançam — dancing two by two,
Спираль вокруг сердца — spiral round the core,
Two great vessels crossing, that's the truncus lore.
[Outro]
PA anterior, aorta atrás — remember the turn,
Спираль на всю жизнь — that's the lesson you'll learn,
Great vessels, branches, veins closing the loop,
Coração, сердце — one continuous troupe.
8. Blue Tides, Red Tidelines
[Verse 1 — Male, Right Side]
Cava superior, cava inferior, feeding the right hall,
Vena cava whispers to the atrium, answering the call,
Tricuspid swings open, three flaps in a row,
Right ventricle loads up, ready to blow,
Pulmonic valve cracks, the artery unwinds,
Blue blood ships out to the lung's tidelines,
Twenty-five over five, that's the pressure I keep,
Low and slow, like a river running deep.
[Verse 2 — Female, Left Side]
Lungs hand it back through four pulmonary veins,
Oxygen riding shotgun, washing out the stains,
Left atrium catches it, mitral doors swing wide,
Left ventricle flexes, thick-walled, full of pride,
Aortic valve fires like a cannon at dawn,
Into the aorta, the whole body's drawn,
One-twenty over eighty, the pressure I command,
High and loud, pushing blood to your hand.
[Chorus]
Right side low, left side glow,
Blue goes to the lungs, red's the body's flow,
Tricuspid, pulmonic — mitral, aortic gate,
Two circuits in series, never sharing a plate,
Never mix, never bleed into each other's lane,
That's the whole heart working, no wire crossed again.
[Verse 3 — Trade lines]
M: Deoxygenated cargo, dim and thick and slow,
F: Oxygenated current, bright and built to go,
M: My side's a puddle pressure, gentle on the wall,
F: My side's a fire hose, answering the call,
M: Same four chambers, different jobs to do,
F: One machine, two systems, running the whole crew.
[Verse 4]
The septum is the border, the wall that keeps the peace,
Foramen ovale closes, the shunting has to cease,
Ductus arteriosus, open when you're new,
Seals within the week, then the split rings true,
Complete separation — the anatomical creed,
Every truncus repair chasing that exact same deed,
Two rivers, banks apart, from the atrium to the aorta,
Cross the wall and you've built yourself a disorder.
[Verse 5]
Cyanotic babies, mixing where it shouldn't be,
Listen for the murmur, that's the leak you'll see,
Echo shows the shunt, the pressure tells the tale,
Catheter confirms it, numbers never fail,
Patch the hole, tie the duct, rebuild the wall again,
Restore the separation, let the two loops reign.
[Bridge]
SVC, IVC, RA, tricuspid, RV,
Pulmonic, PA, lungs — then back to me,
Pulmonary vein, LA, mitral, LV,
Aortic, aorta, body — that's the key.
[Chorus]
Right side low, left side glow,
Blue goes to the lungs, red's the body's flow,
Tricuspid, pulmonic — mitral, aortic gate,
Two circuits in series, never sharing a plate,
Never mix, never bleed into each other's lane,
That's the whole heart working, no wire crossed again.
[Outro]
Two loops, one engine, never crossing wires,
Low side breathing, high side never tires,
Follow the pressure, follow where it's due,
Separate forever — that's the repair we're chasing too.
9. Two Crowns, One Heartbeat
[Verse 1]
Left main splits like a fork in a creek,
LAD runs the front, that's the wall that speaks —
septum and the pump, the muscle's engine bay,
circumflex wraps round, takes the lateral away.
Links, mein Freund, versorgt die Vorderwand,
zwei Äste, zwei Wege, fest in meiner Hand.
Anterior descending feeds the septum's core,
circumflex kisses the side, then it's looking for more.
[Chorus]
Links und rechts, zwei Kronen im Kreis,
left feeds front, right keeps the bottom warm — weiß?
Sinus zündet, AV hält den Schritt,
His trägt den Strom durch die Wand mit.
Left, right, front, and floor —
coronary crown, that's the anatomy lore.
[Verse 2]
Right coronary, quiet worker, unsung role,
feeds the free wall of the right ventricle, that's the goal.
Ninety percent of the time, it's the boss of below —
inferior wall, and it feeds the AV node, ja, so.
Rechte Krone, sie versorgt das, was man vergisst,
aber wenn sie blockiert, dann ist der Rhythmus im Riss.
Occlude the right, and the bottom wall turns pale,
the node loses power — heart block, follow the trail.
[Chorus]
Links und rechts, zwei Kronen im Kreis,
left feeds front, right keeps the bottom warm — weiß?
Sinus zündet, AV hält den Schritt,
His trägt den Strom durch die Wand mit.
Left, right, front, and floor —
coronary crown, that's the anatomy lore.
[Verse 3]
Now the wiring — sinus node, right atrium's spark,
lights the chambers up like a match struck in the dark.
Travels to the AV node, slows the pulse, takes a breath,
gatekeeper timing, keeps the ventricles from death.
Then the Bundle of His, sneaking through the septal wall,
dividing into branches, left and right, standing tall.
Purkinje fibers spread it wide like ivy on a fence,
squeezing the ventricles in perfect, practiced sequence.
[Verse 4]
Collaterals grow quiet when the vessels start to close,
the heart writes its own detour, nobody knows.
Dominance can shift — some hearts favor the right,
some lean on the left to keep the septum bright.
Balanced circulation, a rare and steady hand,
posterior descending choosing where to stand.
Know your anatomy, know the variant's name,
every heart's a map, but never quite the same.
[Bridge]
Surgeon's hand, be careful where you sew —
the His bundle's hidden in that septal row.
Patch a VSD without a map of the line,
you'll sew shut the rhythm, cut the heart's design.
Durch die Wand, verborgen, zart und fein,
ein falscher Stich, und der Takt bricht ein.
[Chorus]
Links und rechts, zwei Kronen im Kreis,
left feeds front, right keeps the bottom warm — weiß?
Sinus zündet, AV hält den Schritt,
His trägt den Strom durch die Wand mit.
Left, right, front, and floor —
coronary crown, that's the anatomy lore.
[Outro]
Sinus, AV, His, and the branching tree,
Purkinje finishes the current, silent and free.
Left feeds front, right feeds floor,
das Herz erzählt — und wir wissen mehr.
10. Dark Tide Rolling to the Pulmonic Gate
[Verse 1]
Start the clock in the vena cava, dark tide rolling in,
Low on oxygen, tired blood clocking back to kin,
Right atrium opens like a lobby door,
Thin-walled chamber priming for the tricuspid tour.
Tricuspid flaps swing, three little sails,
Cell slides through before the pressure prevails,
Right ventricle grips it, thick-walled, quick,
Loads the plunger for the pulmonic kick.
[Chorus]
Cava, atrium, tricuspid gate,
Ventricle pumps it to the pulmonic straight,
Lungs light it up, pulmonary vein sings home,
Left atrium, mitral door, ventricle roams,
Aortic valve opens, aorta's the road,
Ten stations, one cell, carrying the load,
Trace it, trace it, round the double track,
Systemic goes out, pulmonary comes back.
[Verse 2]
Pulmonic valve — three cusps, a springboard cue,
Shoots the cell to the lungs, old air traded for new,
Alveoli whisper, carbon dioxide's the toll,
Oxygen climbs aboard, that swap is the whole goal,
Pulmonary vein — the only vein running bright red,
Carries the fresh cargo to the left atrium bed,
Small room, big job, station number eight,
Mitral valve waiting, bicuspid, don't be late.
[Chorus]
Cava, atrium, tricuspid gate,
Ventricle pumps it to the pulmonic straight,
Lungs light it up, pulmonary vein sings home,
Left atrium, mitral door, ventricle roams,
Aortic valve opens, aorta's the road,
Ten stations, one cell, carrying the load,
Trace it, trace it, round the double track,
Systemic goes out, pulmonary comes back.
[Verse 3]
Left ventricle's the powerhouse, walls thick as a fort,
Squeezes with a force that could clear out a port,
Aortic valve springs — cusps numbering three,
Aorta's the highway, the cell rides free,
Down through the body, organs sipping the tide,
Capillary beds where the oxygen's supplied,
Back to the vena cava, station ten complete,
The loop closes quiet, then the pump beats repeat.
[Verse 4]
Zoom out further, feel the rhythm's design,
Diastole fills soft, systole draws the line,
SA node sparks it, the heart's own drummer boy,
Signal rolls through atria, ventricles employ,
AV node holds a beat, lets the chambers sync,
Purkinje fibers flash quick as a blink,
Every squeeze is timed, every valve on cue,
The whole circuit dances, one continuous view.
[Bridge – Quiz]
Pop quiz, pop quiz — mitral valve springs a leak,
What happens downstream when that seal turns weak?
Backflow to the atrium, pressure starts to climb,
Lungs get flooded — call it edema time.
Now flip it: tricuspid's leaking on the right,
Liver swells thick, ankles puff overnight.
Every valve's a checkpoint, every leak tells a tale,
Read the current backward, or the whole map derails.
[Outro]
Ten stations, one red cell, the map inside your chest,
Trace it forward, trace it back — now you've passed the test.
11. One Road Where Two Should Stand
[Verse 1]
Picture the fork in the road that never splits,
Aorta, pulmonary — meant to be two separate lifts.
But the septum that should carve it, the wall that should divide,
Never shows its face, never takes a side.
So the heart builds one road where two roads should stand,
One great vessel straddling, astride, understand.
It sits on both ventricles like a bridge with no seam,
Pulling blood from either side into one single stream.
Systemic, pulmonary, coronary too —
Every drop of red running through this one flue.
No fork, no filter, no separate lane,
Just one truncal artery carrying the whole terrain.
[Chorus]
One vessel instead of two, that's the flaw in the frame,
Septum never came, so the trunk stays the same.
One valve for both worlds, leaflets loose, leaking slow,
One hole in the wall where the outlet should go.
Say it with me — one instead of two,
The trunk never split, and the wall never grew.
[Verse 2]
Now look at the gatekeeper, the valve at the door,
Should've been two — aortic and pulmonary corps.
Instead it's one truncal valve, guarding one gate,
Three leaflets typical, but don't celebrate —
Sometimes two, sometimes four, cusps thickened and strange,
Dysplastic from the start, day one they don't change.
So blood leaks backward, regurgitation's the name,
A gate built crooked will guard nothing the same.
One valve, one flaw, born tangled at the seed,
Because the septum failed, the valve failed too — a chained deed.
[Chorus]
One vessel instead of two, that's the flaw in the frame,
Septum never came, so the trunk stays the same.
One valve for both worlds, leaflets loose, leaking slow,
One hole in the wall where the outlet should go.
Say it with me — one instead of two,
The trunk never split, and the wall never grew.
[Verse 3]
Underneath the valve, right there in plain sight,
A gap ten to fifteen millimeters wide,
Subarterial, sitting just below the crown,
The outlet septum missing — the whole wall torn down.
Don't call this a bystander, don't call it a twin defect,
It's the same failed tissue, same broken architect.
One structure was meant to do two jobs at once:
Divide the trunk above, close the floor below.
When that builder collapses, both jobs go unmet —
One flaw, two failures, that's the truncus threat.
[Bridge]
Two vessels dreamed, only one arrived,
Two valves imagined, one gate survived,
Two walls intended, one gap denied —
Everything downstream traces back to this divide.
[Chorus]
One vessel instead of two, that's the flaw in the frame,
Septum never came, so the trunk stays the same.
One valve for both worlds, leaflets loose, leaking slow,
One hole in the wall where the outlet should go.
Say it with me — one instead of two,
The trunk never split, and the wall never grew.
[Outro]
One trunk, one valve, one gap beneath —
Three faces of a single missing sheath.
Remember the root before you name the disease:
One vessel instead of two — that's the key.
12. No Trunk, Two Holes, No Bridge
[Verse 1]
Type Two don't build a bridge, it burns it at the source,
no pulmonary trunk, no highway, no of course.
Where Type One kept a stub, a short little stem,
Type Two erased it clean, no MPA, no A1 kin.
The truncus splits its wall like paper torn in half,
two ostia punched out, posterior, no shaft.
Van Praagh calls it A2, memorize the code—
absence of the trunk is the sign that you're told.
[Chorus]
Dos agujeros, no hay tronco aquí,
posterior wall, that's the ostia's home, sí.
Type Two, Tipo Dos, separate but close,
RPA, LPA, right where the wall goes.
No hay tronco, no trunk, remember the rule—
sin tronco pulmonar, that's the Type Two school.
[Verse 2]
Picture the back wall like a duplex, side by each,
right and left artery got their own private breach.
Not one hole branching like a fork in the road—
two distinct openings, that's the anatomy code.
Adjacent, posterolateral, close but they're apart,
no shared chamber, no common departure cart.
Type One's a fork, Type Two's a pair of twin doors,
memorize the wall, not the vessel that pours.
[Chorus]
Dos agujeros, no hay tronco aquí,
posterior wall, that's the ostia's home, sí.
Type Two, Tipo Dos, separate but close,
RPA, LPA, right where the wall goes.
No hay tronco, no trunk, remember the rule—
sin tronco pulmonar, that's the Type Two school.
[Verse 3]
Now the twist, the spiral, the crossed anatomy game—
LPA rides anterior, superior, stakes its claim,
while the RPA dips posterior, inferior, low,
crossing paths mid-flight before the lungs they go.
Or flip the script, reverse it, the pattern still applies,
branches interlace like ribbons under the skies.
Not a fault, a variant, teach it as it's seen—
crossed courses live inside the borders of Type Two's scene.
[Bridge]
Millimeters, mira, that's the argument's edge—
a stub so short it teeters on the ledge.
Borderline entre Uno y Dos, a fuzzy line,
call it a continuum, not a rigid sign.
Anatomy don't always fit the boxes that we drew—
sometimes the truth is somewhere in between the two.
[Verse 4]
Surgeons at the table, tracing every seam,
counting up the ostia before they plan the scheme.
Echo and the angio, cath lab confirms the view,
CT reconstructs the wall to prove it's really Two.
Because the repair changes with the pattern that you find,
patch it wrong and the pressures fall behind.
So the classroom chant becomes the operating creed—
know your ostia, know the wall, know exactly what you need.
[Chorus]
Dos agujeros, no hay tronco aquí,
posterior wall, that's the ostia's home, sí.
Type Two, Tipo Dos, separate but close,
RPA, LPA, right where the wall goes.
No hay tronco, no trunk, remember the rule—
sin tronco pulmonar, that's the Type Two school.
[Outro]
No trunk, twin doors, the crossing overhead—
Type Two, tipo dos, now it's stitched in your head.
13. One Trunk, One Truncal Key
[Verse 1]
(Male)
Lesson one was clean: two loops, never crossing,
RA feeds RV, pulmonary door, no tossing,
LA feeds LV, aortic door, straight to the body,
Two lanes, two valves, separate and steady.
(Female)
Rewrite the diagram, watch the wiring fail—
RV and LV both dumping through one rail,
No wall between them, just a hole called VSD,
Mixing bowl of chambers, one truncal valve, one key.
[Chorus]
Two ventricles, one door, that's the tell,
Truncus means the split never fell in place—
One trunk splits three ways, hear the mnemonic swell:
Lungs, body, heart — one root, one face.
RPA, LPA, ostia carved like twins,
Arch keeps rolling, coronary river begins.
One vessel wearing three different skins.
[Verse 2]
(Female)
Follow the blend past the truncal gate,
Oxygen-rich, oxygen-poor, sharing one plate,
Purple-tinted lips, a whisper not a shout,
Mild cyanosis — the mixing giving it out.
(Male)
No pulmonary valve standing sentry at the door,
So lung vessels catch pressure meant for the shore
Of the aorta — systemic force unchecked,
A flood in miniature, a nursery wreck.
[Verse 3]
(Male)
Weeks one through six, the lung resistance drops,
Blood that should trickle now absolutely never stops,
Fast little breaths, feeding turns to a fight,
Growth curve stalling — heart failure by candlelight.
(Female)
This is the hinge, the reason surgeons race the clock,
Untreated, arterioles harden, thicken, lock —
Sclerotic little tunnels, defensive and irreversible,
Mortality was brutal, eighty percent, incorrigible.
[Chorus]
Two ventricles, one door, that's the tell,
Truncus means the split never fell in place—
One trunk splits three ways, hear the mnemonic swell:
Lungs, body, heart — one root, one face.
RPA, LPA, ostia carved like twins,
Arch keeps rolling, coronary river begins.
One vessel wearing three different skins.
[Verse 4]
(Male)
Echo shows the straddle, one vessel overriding wide,
Catheter confirms the pressures equalized inside,
Four types by Collett, branching tells the tale,
Type one splits early, type three sends the lungs a separate rail.
(Female)
Surgeons map the coronaries before they cut the trunk,
Homograft conduit rises where the pulmonary sunk,
Rastelli's legacy lives on in every stitch,
Turning one river into two, closing up the ditch.
[Bridge]
(Male, urgent)
Neonatal window, no lingering, no maybe—
(Female, tense)
Cut before the vessels calcify like old rope,
Before the flood becomes an inexorable slope,
Repair the fork the embryo forgot to make.
(Both)
One trunk, three roads — fix it before it's too late.
[Outro]
(Female, fading)
RA, RV — VSD — one truncal gate,
Lungs and body and heart share a single fate.
(Male)
Ostia open, arch bends round the bay —
One river, three mouths, cut it clean today.
14. Mirror Image Over the Bronchus
[Verse 1]
Trace the arch up from the truncus, watch it lean to the right side,
Crossing over the right bronchus, that's the tell, that's the guide,
Quarter to a third of these babies wear the arch reversed like a mirror,
Left brachiocephalic goes first now, then right carotid comes clearer,
Right subclavian trailing last, the whole branch order's flipped inside out,
Same players, opposite stage — that's what mirror-image is about.
[Chorus]
Right arch bending over that bronchus, small hole breathing between the atria,
Thick valve leaking or choking traffic, coronaries hiding in strange behavior,
Thirty percent losing a piece of twenty-two, calcium dropping, thymus running thin,
No ductus waiting in the wings — this is the anatomy that rides with Type Two.
[Verse 2]
Now peek at the septum, don't panic, there's a modest little door,
A patent foramen, sometimes an ASD, a shunt that's small, not a flood on the floor,
Blood sneaks through at the atrial level, pressures find their common ground,
It's the quiet cousin at the table, rarely loud, but always around.
[Verse 3]
That single truncal valve is working overtime, doing aortic and pulmonic duty,
Leaflets thickened, dysplastic, stealing away at its beauty,
Might leak backward — regurgitation, might choke forward — stenosis instead,
Surgeons listen to that valve's story before they touch a single thread.
Then chase the coronaries like buried wire, one ostium or a wandering course,
Map them out before the RV incision, cut wrong and you cut off the source.
[Chorus]
Right arch bending over that bronchus, small hole breathing between the atria,
Thick valve leaking or choking traffic, coronaries hiding in strange behavior,
Thirty percent losing a piece of twenty-two, calcium dropping, thymus running thin,
No ductus waiting in the wings — this is the anatomy that rides with Type Two.
[Bridge]
Twenty-two Q eleven, the microdeletion creeping in the genes,
Thymus shrunk down to a whisper, immune defenses running lean,
Calcium sliding low on the numbers, watch it close before the knife,
Irradiated blood in the bag now, protecting a fragile little life.
And the ductus? Usually silent, closed up, nothing left to trace —
Unless the arch itself is broken, then it's holding open space.
[Verse 4]
So map the vessels, count the genes, check the calcium in the blood,
This isn't chaos, it's a pattern — a package, understood.
Right arch, small hole, sick valve, sly coronary, thin thymus, quiet duct,
Six companions riding shotgun every time the truncus gets constructed.
[Chorus]
Right arch bending over that bronchus, small hole breathing between the atria,
Thick valve leaking or choking traffic, coronaries hiding in strange behavior,
Thirty percent losing a piece of twenty-two, calcium dropping, thymus running thin,
No ductus waiting in the wings — this is the anatomy that rides with Type Two.
15. One Trunk, Four Truths
[Verse 1]
Two vessels leaving a healthy chest,
Aorta struts left, pulmonary flexes right,
Each got a valve doing gatekeeper best,
Septum's sealed tight, no room for a fight,
Oxygen-rich cruises out through the arch,
Oxygen-poor ships out to the lung's back porch,
That's the blueprint, normal and true,
Now flip the chart — let's meet type II.
[Chorus]
Four differences, hear the call,
Valve's a ghost, there's no MPA at all,
One hole punched clean through the septum wall,
Single trunk doing the job for all,
PA ostia sprout where the branches fall,
That's your truncus map, don't let it stall,
Vanish, split, merge, and sprout,
Label 'em side by side, that's what it's about.
[Verse 2]
Look for the valve where the pulmonary used to sit,
It's absent, ghosted, erased from the script,
No main pulmonary artery stem in the frame,
That's difference number one, learn the name,
Next slide down to the ventricle floor,
A VSD's grinning, a hole in the core,
Blood don't care 'bout borders no more,
Left and right mixing, equalized for sure,
Instead of two roots you got a single trunk,
Aorta and pulmonary fused, no longer chunked,
One vessel doing double duty, overworked,
And where the branches used to fork from their own berth,
Now the pulmonary ostia perch right on the trunk itself,
Riding the wall like a hitchhiker's health,
Four fixes to label, four flags on the chart,
Compare 'em side by side — that's the art.
[Chorus]
Four differences, hear the call,
Valve's a ghost, there's no MPA at all,
One hole punched clean through the septum wall,
Single trunk doing the job for all,
PA ostia sprout where the branches fall,
That's your truncus map, don't let it stall,
Vanish, split, merge, and sprout,
Label 'em side by side, that's what it's about.
[Verse 3]
Now let's chase the oxygen, follow the tide,
Right atrium's still low, seventy give or take, nothing to hide,
It rolls through tricuspid, meets the right ventricle's crowd,
But that VSD's open, so the mixing's loud,
Left ventricle's rich blood spills through the gap,
Right and left ventricle sats basically overlap,
Call it eighty-five, roughly, both sides the same,
'Cause pre-truncal mixing rewrote the game,
Climb into the trunk, the single great vessel bed,
Same number holds, eighty-five instead,
Branch off to the lungs, branch off to the head,
Same saturation, no gradient ahead,
That's the tell — no step-up, no drop,
One number rules from the valve to the top,
Cyanotic baby, low but steady sats,
'Cause the trunk don't discriminate, that's just facts.
[Bridge]
Side by side, chart by chart, don't blend the lines,
Circle the ghost valve, circle the vessel that combines,
Circle the hole, circle the sprouting signs,
Four circles drawn and the diagnosis shines.
[Outro]
Vanish, split, merge, and sprout,
Eighty-five percent, that's what it's about,
Truncus type II, now you've got the sound,
Label it, trace it — you already found it.
16. One Button, No Miss
[Verse 1]
One vessel used to carry it all,
lungs and body drinking from a single stone wall,
first move of the surgeon: peel the branches away,
snip both PA ostia where they cling and they stay.
Type two, they're neighbors, close enough to kiss,
lift them off together, one button, no miss,
now there's a window left open in the trunk,
glutaraldehyde-treated pericardium sunk
into that gap, stitched tight like a seal,
lungs disconnected — first goal made real.
[Chorus]
Three goals, one wire back to true —
snip the branch, steer the stream, span the avenue,
patch the hole, patch the wall, build the tube anew,
rewire the diagram, that's what we do.
Separate. Redirect. Rebuild the road.
Three goals carry the whole heart's load.
[Verse 2]
Second move dives down through the wall of the heart,
that hole between chambers gets closed like a chart,
the patch is angled, positioned with care,
so the left ventricle's pushing through open air
straight to the trunk, no detour, no bend,
and the valve that once was truncal — hear the name transcend:
call it the neo-aortic, the vessel's new crown,
the neo-aorta wears what the trunk handed down.
Same architecture, brand new career,
the plumbing's ancient, the title is here.
[Chorus]
Three goals, one wire back to true —
snip the branch, steer the stream, span the avenue,
patch the hole, patch the wall, build the tube anew,
rewire the diagram, that's what we do.
Separate. Redirect. Rebuild the road.
Three goals carry the whole heart's load.
[Verse 3]
Third move builds a bridge where the right heart had none,
cut a window in the RV, that's where it's begun,
a conduit spans it, running up to the split
where the pulmonary arteries wait to be knit.
Homograft's the gold standard, borrowed and true,
a stranger's own pipeline carrying blood through,
xenograft's the bovine jugular vein instead,
Contegra by name, cow tissue widespread,
Gore-Tex tube for the neonate, ten to twelve wide,
or skip the conduit — Barbero-Marcial's stitched it inside.
[Bridge]
Lungs cut loose, patched and sealed,
left ventricle's new pathway revealed,
right side rebuilt with a borrowed lane —
three moves, one circuit, no vessel in vain.
Snip. Patch. Connect. Say it again.
Snip. Patch. Connect. Say it again.
[Chorus]
Three goals, one wire back to true —
snip the branch, steer the stream, span the avenue,
patch the hole, patch the wall, build the tube anew,
rewire the diagram, that's what we do.
Separate. Redirect. Rebuild the road.
Three goals carry the whole heart's load.
[Outro]
Separate the lungs, close the hole, raise the tube high,
the diagram's rewired — watch the circulation fly.
Three goals, one heart, singing clean and new,
that's the truncus repair, wired straight through.
17. Stitched Hearts, Steady Beat
[Verse 1]
Male: Right atrium chillin', tricuspid door still swings the same,
Nothing touched the inflow, no rerouting, no rename,
Right ventricle took the hit, that ventriculotomy's the scar,
Surgeon paved a new road where the old outflow tract once was,
Native chamber, borrowed exit, pumping low and slow to lungs,
Pressure eased, that's the goal, less strain on muscle rungs.
Female: But that wall remembers cutting, holds the memory of the blade,
Function's steady, structure's altered, that's the price the fix has paid,
It's the landmark for the surgeon tracing conduit from the start,
Right ventricle to pulmonary — carve it into your chart.
[Chorus]
Both: RA to tricuspid, RV to the graft,
Branch PAs catch the current, lungs collect the draft,
LA to mitral, LV to the patch,
Steering cross the septum to the neo-aortic hatch,
Neo-aorta carries on, coronaries ride along,
That's the whole repaired connection, that's the mnemonic song.
[Verse 2]
Female: That valved conduit's a loaner, prosthetic, graft, not grown,
Every other structure's native — this one stands alone,
Calcium creeps in slowly, gradient climbing up the chart,
Achilles heel of the whole repair, remember that part,
Where they stitched the branches on, watch the anastomosis seam,
Stenosis loves a narrow scar — that's no place to daydream.
Male: RPA, LPA, reimplanted, fed by graft,
Echo, cath lab, MRI keep tracking down that draft.
[Verse 3]
Male: Left atrium, mitral valve, untouched, running clean,
Left ventricle drives the blood, the strongman of the machine,
But the septum's got a patch where the hole was stitched up tight,
Female: VSD patch redirects it, sends the flow to outflow right,
Tiny leaks around the border, a millimeter, maybe two,
Reshunting's usually harmless — nothing new to lose sleep to.
[Verse 4]
Male: That truncal valve turned neo-aortic, native but not built quite whole,
Congenitally imperfect, regurgitation takes its toll,
Root can widen, slow and steady, watch it every single year,
Female: Coronaries branch off native, from that very root right here,
Unchanged since the very first stitch, feeding muscle, feeding wall,
Male: Arch stays wherever it started — right or left, it doesn't fall
back to some "normal" bending, surgery won't move that curve,
Whatever side it launched from, that's the side it'll still serve.
[Chorus]
Both: RA to tricuspid, RV to the graft,
Branch PAs catch the current, lungs collect the draft,
LA to mitral, LV to the patch,
Steering cross the septum to the neo-aortic hatch,
Neo-aorta carries on, coronaries ride along,
That's the whole repaired connection, that's the mnemonic song.
[Bridge]
Male: One side native, growing strong, the other capped in plastic,
Female: Follow-up ain't optional, this fix was never elastic,
Both: Surveillance every season — echo, gradient, valve,
Watch the graft, watch the root, that's how the heart behaves.
18. Stitched Together, Beating On
[Verse 1]
Twelve millimeters, stitched in a body four kilos light,
that tube was measured for an infant, not for future height.
Thirty kilos coming, the femur stretching wide,
but the conduit stays frozen — no cells divide inside.
Calcium courts the leaflets, stiffening like dried clay,
stenosis creeping narrow, regurgitation seeps away.
Echo gradients climbing, month by month they rise,
this ain't some grim surprise, it's the expected size.
[Chorus]
El corazón remendado, not a heart that's whole and free,
one prosthetic link is holding — watch it, corazón, watch it lifelong, sí.
Não é normal, mas é vida — the plumbing runs in series now,
parallel became a highway, but the bridge needs mending somehow.
[Verse 2]
First we reach it with a catheter, balloon opens up the lane,
a stent props the corridor before it narrows again.
Melody, SAPIEN — a valve folded on a wire,
percutaneous placement, tucked inside the old attire.
But balloons and stents are borrowed time, not the final say,
most patients meet a surgeon before their twenties, on the way —
conduit replacement, maybe two, maybe three,
the toll charged on the highway built from mixing to a series.
[Chorus]
El corazón remendado, not a heart that's whole and free,
one prosthetic link is holding — watch it, corazón, watch it lifelong, sí.
Não é normal, mas é vida — the plumbing runs in series now,
parallel became a highway, but the bridge needs mending somehow.
[Verse 3]
The neo-aortic valve was pulmonary, built for softer strain,
now it's bracing systemic pressure, feeling all that gain.
Regurgitation grows, the root may stretch and swell,
some walk toward a valve job dressed in a borrowed shell.
Branch PA's got narrowing where they sewed the seam —
balloon it, stent it, keep the lung fields in the stream.
The VSD patch mostly holds, a trivial little leak,
we watch it every visit, calm, we never lose our sleep.
[Bridge]
El sistema de conducción lies right beside that patch,
heart block comes uninvited, so we monitor and catch.
Prosthetic material, ricos em risco de infecção —
brush your teeth like scripture, antibiotics, proteção.
Não é falha, é física — plastic doesn't multiply,
we surveil this heart forever, corazón, até o fim.
[Chorus]
El corazón remendado, not a heart that's whole and free,
one prosthetic link is holding — watch it, corazón, watch it lifelong, sí.
Não é normal, mas é vida — the plumbing runs in series now,
parallel became a highway, but the bridge needs mending somehow.
[Outro]
Series circuit, one true seam to keep,
lifelong watching while the old scar sleeps.
Corazón remendado, para siempre vigilar,
não é normal — mas segue a bater, segue a bater.
19. Follow the Beat of the Heart
[Verse 1]
One vessel outta two ventricles — that's the truncus tale,
Healthy heart's got two roads split: aorta and pulmonary trail,
Left ventricle feeds the body, right one feeds the lung,
Two separate highways, that's the tune the steady heart has sung,
Draw it clean — aorta arching, pulmonary artery low,
Semilunar gates deciding exactly where the blood can flow.
[Chorus]
Dibuja el corazón, memory on the page,
Normal, truncus, repaired — tres dibujos, one stage,
Sígueme el problema, follow where the pressure hides,
Corazón sano, roto, fixed — draw all three, no guide.
[Verse 2]
Now truncus arteriosus type two, the split never came,
One trunk carries everything — aorta, pulmonary, same name,
Branch pulmonary arteries rising near the top,
Off the common trunk before the arch can even drop,
One truncal valve, leaflets straddling the crest,
VSD sitting underneath — that's the override test,
This ain't two lanes merging, it never split at all,
One vessel wearing two coats, standing tall.
[Chorus]
Dibuja el corazón, memory on the page,
Normal, truncus, repaired — tres dibujos, one stage,
Sígueme el problema, follow where the pressure hides,
Corazón sano, roto, fixed — draw all three, no guide.
[Verse 3]
Post-repair the picture shifts, surgeons built a bridge,
Conduit connects the right ventricle up over the ridge,
Homograft or synthetic tube, routing blood to the lung,
Truncal root gets promoted, neo-aorta, young,
This repaired diagram's no blank slate wiped clean —
It's a palimpsest, old anatomy still ghostly seen,
Underneath the surgeon's ink the truncal root remains,
Layered history sketched in every scar and seam.
[Bridge]
Echo says the conduit gradient's sitting at sixty-seven,
RV pressure ninety — that ain't casual, that ain't even,
Locate it: right ventricle straining past the tube,
Stenosis pinching the channel, outflow overdue,
Next step — think it through, don't just chart and roam,
Cath lab checks the numbers, echo calls you home,
Balloon it, stent it, or ring the surgeon for a swap,
Follow the problem to the conduit — that's where the workup stops.
[Chorus]
Dibuja el corazón, memory on the page,
Normal, truncus, repaired — tres dibujos, one stage,
Sígueme el problema, follow where the pressure hides,
Corazón sano, roto, fixed — draw all three, no guide.
[Outro]
Three diagrams, one page, sin trampa, from your mind,
Normal, truncus, repaired — leave nothing behind,
Sígueme el problema, trace the pressure to its source,
Draw it, name it, fix it — that's the cardiac course.
20. Questions That Beat Like a Heart
[Verse 1]
Listen how the conus septum forgot to arrive,
One great vessel, both ventricles feeding inside,
The infundibular septum's absent, that's the crime,
So the hole beneath the valve was written into design.
Call it "associated," and you'd be telling a lie,
It's the malalignment where the trunk overrides,
Same failure of septation, same broken divide,
The VSD's the truncus's twin, born on the same tide.
[Chorus]
Hold the hole — it's part of the plan,
Match the mouth where the button began,
Watch the growth, the heart's still in your hand,
Trace the arch where the vessels ran.
[Verse 2]
Type two, the arteries huddle up close, sharing one lip of tissue, a single duct root,
Cut one wide button, both mouths ride along,
Sutured back easy — the geometry sings its own song.
Type three, the vessels split, they've drifted apart,
Each ostium alone, closer to the valve's own heart,
Carve that button now, you risk the commissure's line,
Distort one leaflet, you've distorted the whole design.
[Chorus]
Hold the hole — it's part of the plan,
Match the mouth where the button began,
Watch the growth, the heart's still in your hand,
Trace the arch where the vessels ran.
[Verse 3]
Complete don't mean finished, it means today's repair,
The homograft you sewed in won't grow with the heir,
Calcium creeps in, the conduit tightens its grip,
The truncal leaflets thicken, they warp, they slip.
Rhythm can wander where the patch meets the wall,
Years down the road bring a different recall,
So echo, and holter, and cath every stage —
Complete is a chapter, not the end of the page.
[Verse 4]
Flip the arch to the right, and the order reverses,
First vessel off: the left brachiocephalic disperses,
Then the right carotid climbs its own private stair,
Then the right subclavian breathing separate air.
Mirror-image branching, predictable, neat,
Pairs with tetralogy, pairs with truncus's beat,
But when the left subclavian trails off alone,
A vascular ring may circle the windpipe's own home.
[Bridge]
Four questions, one chest, one truth laid bare,
The defect, the button, the years, the air,
Anatomy whispers what pathology wrote,
Listen closer — the heart keeps its own footnote.
[Chorus]
Hold the hole — it's part of the plan,
Match the mouth where the button began,
Watch the growth, the heart's still in your hand,
Trace the arch where the vessels ran.
[Outro]
Not associated — woven in the frame,
Type two, type three — geometry's the name,
Complete repair still answers to the calendar's claim,
Right arch, mirrored branches — same vessels, new aim.
21. Heartbeat Rotation, Station to Station
[Verse 1]
Freeze the frame, echo's rolling, four chambers on the screen,
Trunk sits saddled on the septum, one vessel, one machine,
Follow the sweep past the valve where the PA ostia hide,
Type II keeps 'em close together, posterior, side by side,
CT angiogram spins it slow, three-sixty, no more guessing,
Normal heart, then the defect, then the fix we're second-guessing,
Spot the VSD like a doorway punched beneath the crest,
Chambers, trunk, and holes — advanced eyes pass the test.
[Chorus]
One trunk, two roads, VSD's the open floor,
Count the ostia, trace the arch, that's the cardiac practical law,
Echo, CT, printed heart, diagram, then the chart,
Four stations, one rhythm — anatomy's the art.
[Verse 2]
Now the model's in your palm, resin cooled and true,
Three hearts on the table — normal, defect, and post-repair too,
Run your finger where the trunk forks off before the split,
Feel the conoventricular gap, malalignment, the misfit,
Turn it over, right arch curling like a backwards question mark,
Spiral branch pulmonaries twisting, corkscrewed through the dark,
This ain't textbook flat — it's contour, depth, and weight,
Palpate the pathology before you palpate fate.
[Chorus]
One trunk, two roads, VSD's the open floor,
Count the ostia, trace the arch, that's the cardiac practical law,
Echo, CT, printed heart, diagram, then the chart,
Four stations, one rhythm — anatomy's the art.
[Verse 3]
Blank page, dotted outline, no labels, only lines,
Name the trunk, the VSD, the ostia, and the signs,
Normal sheet beside the type II, beside the post-op view,
Pencil down what's missing — annotate what's true,
Right ventricle, left ventricle, the valve that overrides,
Draw the conduit corridor where the old trunk subdivides,
Full credit's in the labels, not the sketch you underline,
Precision beats a pretty picture every single time.
[Verse 4]
Baby born, murmur heard, day one on the chart,
Type II confirmed — spiral PAs, right arch from the start,
Complete repair goes in, twelve-millimeter conduit laid,
Narrate it: trunk detached, VSD patched, pathway remade,
Months pass, gradient climbing, conduit's getting tight,
Echo shows the narrowing, catheter lab tonight,
Balloon inflates the stenosis, pressure gradient falls,
Tell the story chamber by chamber — that's what the case recalls.
[Bridge]
Trunk to VSD to ostia to arch,
Say it walking through the imaging, don't lose the march,
Model, diagram, echo, case — same anatomy, four lenses,
Advanced recall means no station catches your defenses.
[Chorus]
One trunk, two roads, VSD's the open floor,
Count the ostia, trace the arch, that's the cardiac practical law,
Echo, CT, printed heart, diagram, then the chart,
Four stations, one rhythm — anatomy's the art.
[Outro]
Trunk, VSD, ostia, arch — say it till it's memorized,
Type II, post-repair, normal — every state internalized.
22. Heartbeat Under Pressure
[Verse 1]
Forty points on paper, structures inked in ink,
Superior vena cava feeding right atrium's brink,
Tricuspid drops the cargo, pulmonary valve exhales,
Through the lungs, back to left side, oxygen retails,
Mitral opens quiet, aorta takes the crown,
Now flip the script to broken hearts, the ones turned upside down,
Tetralogy's four crimes, transposition's swapped design,
Draw the septum, label the shunt, get every artery in line.
[Chorus]
Forty, thirty, twenty, ten — write it, work it, speak it, live it,
Three hearts beating in my skull, I gotta give it,
Forty for the paper trail of vessel and valve,
Thirty for the station where your fingers do the calc,
Twenty for the tongue tracing blood from door to door,
Ten for showing up and asking one more question at the core.
[Verse 2]
Thirty on the stations, plastic models on the table,
Blindfold on my fingertips, I'm reading every cable,
Palpate the patch, find the baffle, name the graft by touch,
Mustard, Senning, Fontan — the plumbing they reroute,
Station five's the stethoscope, murmur whispers where it's torn,
Station six a slide of trabeculae, ridges fleshy, lining walls unworn,
Ninety seconds on the clock, ticking like a quiet war,
Precision beats my panic, that's the lesson at the core.
[Verse 3]
Twenty for the oral, sit me down and watch me sweat,
Trace the caval highway, don't you dare forget,
Heart of the healthy, atria talk in sync, no static,
Heart with cor triatriatum — split in three, dramatic,
A membrane hides inside the atrium, cutting flow in half,
Heart three's the single ventricle, Fontan's the surgical path,
Explain the patch, the baffle, why the shunt was built to save,
Silence costs me points, my voice must walk the maze I made.
[Verse 4]
Four hearts laid out in silicone, wax and wire and thread,
Study the coronary sinus, follow where the vessels spread,
Every valve's a checkpoint, every chamber holds its name,
Ductus arteriosus closing, marking how the fetal changed,
Foramen ovale sealing, pressure shifting side to side,
Anomalous return misrouting where the bloodflow's tried,
Pass the practical, pass the written, master the whole game,
Every crooked heart still beats — that's the truth I came to claim.
[Bridge]
Ten percent for showing up with your hand already high,
Asking why the septum failed, asking how and why,
Participation's not a freebie, it's the pulse that keeps the room alive,
Four percentages, one exam, only one way to survive.
[Chorus]
Forty, thirty, twenty, ten — write it, work it, speak it, live it,
Three hearts beating in my skull, I gotta give it,
Forty for the paper trail of vessel and valve,
Thirty for the station where your fingers do the calc,
Twenty for the tongue tracing blood from door to door,
Ten for showing up and asking one more question at the core.
[Outro]
Three hearts, four numbers, one relentless test,
Trace it, touch it, speak it — then you've passed the rest.
23. Heartbeat of Mastery
[Verse 1]
Right atrium opens where the vena cavae pour their tide,
Tricuspid valve swings the blue blood to the right ventricle's side,
Pulmonic valve fires it up the pulmonary trunk in flight,
Lungs trade the carbon for oxygen, hand it back pure and bright.
Pulmonary veins deliver red cargo to the left atrium's floor,
Mitral valve, the quiet usher, opens the ventricle's door,
Aortic valve's the final gate, the body's only ramp,
Atrial septum splits the tops, ventricular septum stands the damp.
[Chorus]
Blue goes right, red goes left, that's the wall between,
Atrium, valve, ventricle, valve — memorize the routine,
Cavae in, aorta out, the four-beat trail don't fail,
Name the chamber, name the vessel, walk the whole loop's tale.
[Verse 2]
Now picture the ridge that never finished its splitting,
Aorticopulmonary wall just quit its knitting,
One trunk, one valve straddles the hole where two should be,
Coronaries and lung roots share a single tree.
Four changes tell it: no division of the great vessel,
One truncal valve alone runs the semilunar wrestle,
Pulmonary branches sprout off the trunk, not the right ventricle's floor,
And a gaping septal breach where a wall should close the door.
Type two ostial pattern — the branches, close and shy,
Separate little openings, side by side, not stacked up high.
[Chorus]
[Verse 3]
Surgeons chase three goals, a triad carved in bone:
Sever the lung's own river from the truncal throne,
Patch the septal gap so the truncal valve stands alone,
crowned as the aortic gate, systemic and known,
Then bridge right ventricle to lungs with a conduit freshly sewn.
Finished heart: the truncal valve wears the aortic crown,
VSD patched, one clean pathway down,
Right ventricle reaches skyward through a valved, grafted lane —
a borrowed tunnel standing in for a highway nature failed to sustain.
[Bridge]
That conduit's not living tissue — it won't stretch, it won't grow,
Calcium finds its lattice, narrowing the flow,
Senescence creeps in quiet, that's the tissue's slow decay,
So echo, cath, and watchful eyes must circle every year that stays.
No fix is ever final when the graft's a borrowed stone,
Lifelong follow-up's the toll for a highway not your own.
[Chorus]
[Verse 4]
Embryology's clock stalls where the septum should divide,
Neural crest cells wander, lost before they reach the truncal side,
One vessel, one valve, one root for the body and the lung,
Truncus arteriosus — the name where this tale begun.
[Outro]
Chamber, valve, septum, vessel — trace the circuit clean,
Truncus, ostia, conduit — say exactly what you've seen,
Mastery's no whisper, it's the whole map, sung complete —
inflow, outflow, repair, and watch — the heart's whole architecture, on repeat.
