[Verse 1 - Male]
Membranous, muscular, inlet and outlet too,
Four little doorways where the septum falls through.
Roger's murmur, Eisenmenger's slow reversal,
Natural history written in a pressure gradient's rehearsal.
Thirty-five percent rides on this ink and this page,
Classification carved into the anatomic stage.
[Verse 2 - Female]
Echo probe gliding, color flow paints the shunt,
Left-to-right jet screaming where the muscle meets the front.
Spot the aneurysm, catch the aortic cusp that's prolapsing,
Endocarditis vegetations quietly collapsing.
Twenty-five percent for the pictures that don't lie,
Read the chamber sizes, name the type, don't guess and don't rely.
[Chorus]
Thirty-five for the page, twenty-five for the frame,
Twenty-five at the bedside, calling out the name,
Fifteen for the rare one, the lesion left to chase—
Four numbers, one mastery, welcome to the case.
Write it, see it, decide it, defend it,
Ventricular septum, that's how we comprehend it.
[Verse 3 - Duet]
Male: When do we close it? Resistance in the lung—
Female: Qp over Qs, the ratio's already sung.
Male: Surgical patch or a catheter's device,
Female: Timing is everything, don't ask us twice.
Both: Twenty-five percent for the choice that you defend,
Pulmonary hypertension waits for no weekend.
[Verse 4 - Female]
Now step past the septum, into Module Six terrain,
Truncus or Tetralogy — pick one, explain the strain.
Fifteen percent for the lesion beyond the common floor,
Show us you can wander and still find the door.
[Verse 5 - Male]
Embryology whispers where the conus twists and turns,
Malalignment tells the tale the fetal heart still learns.
Sizing up the defect, restrictive or unrestrictive flow,
Every gradient a clue to where the pressures go.
Follow the conduction, the bundle finds its way,
Around the borders of the hole, don't let the block delay.
Watch the AV node, respect the danger zone,
Every repair a lesson written in the surgeon's tone.
[Bridge - Male]
One hole becomes a hundred questions deep,
Every murmur a promise that the tissue didn't keep.
[Female]
Every catheter a sentence in the story we transcribe,
[Both]
Every score a heartbeat of the ventricle inside.
[Chorus]
Thirty-five for the page, twenty-five for the frame,
Twenty-five at the bedside, calling out the name,
Fifteen for the rare one, the lesion left to chase—
Four numbers, one mastery, welcome to the case.
Write it, see it, decide it, defend it,
Ventricular septum, that's how we comprehend it.
[Outro - Duet]
Membranous, muscular, echo and the plan,
Four percentages sewn into a single, steady span.
Close the gap, name the type, defend it 'til the end—
That's the final assessment, that's the story we transcend.
