[Verse 1]
Clock starts ticking on the day of birth,
one great vessel doing double the work,
four to six weeks, that's the window we chase,
before the lungs flood and the shunt wins the race.
Type Two whispers where the branches sit close,
both pulmonary mouths on a shared little coast,
so tight together, so near the same wall,
that's the edge we're given, the gift in it all.
[Chorus]
Single button, cuff of truncal wall,
one clean snip frees the pair of ostia both,
Six weeks or sooner, don't let it stall,
Spiral steer wide, no kink, no coax.
Patch it, plumb it, protect the node,
Right vent opens on the avascular road,
Single button, six-week code —
sing it back so the graft never blows.
[Verse 2]
Excise the ostia together as one,
en bloc with a collar where the truncal wall spun,
Type Two's the favor Type Three never gets,
adjacent openings, no separate frets.
The aorta's left with a gap in the seam,
sew it shut direct or bridge it with a gleam
of glutaraldehyde pericardium spread,
autologous tissue, treated and fed.
[Verse 3]
Now watch the spiral where the vessels twist behind,
orient that conduit or you'll strangle the line,
kink the left, choke the right, and the flow runs dry,
sometimes translocate, reimplant, don't ask why.
Cut the right ventricle where the vessels won't run,
avascular window, coronary map done,
trace the artery before the knife finds its place,
skip that step and you can't save face.
[Chorus]
Single button, cuff of truncal wall,
one clean snip frees the pair of ostia both,
Six weeks or sooner, don't let it stall,
Spiral steer wide, no kink, no coax.
Patch it, plumb it, protect the node,
Right vent opens on the avascular road,
Single button, six-week code —
sing it back so the graft never blows.
[Verse 4]
The VSD's subarterial, patched from the right,
right atrial window keeps the conduction in sight,
sometimes a ventriculotomy opens the view,
but the bundle stays sacred — that's rule number two.
Homograft's the standard, the gold in the bank,
Contegra the xenograft waiting in rank,
Gore-Tex when the shelf runs empty and bare,
ten to twelve millimeters, the neonate's wear.
[Bridge]
Barbero-Marcial skips the conduit chain,
direct RV-to-PA, less plastic, less strain,
Right arch bending? Cannulate with care,
reangle the conduit, mind what's not there,
Sternum stays open when the heart's still swollen and tight,
delayed closure buys the tissue its quiet respite.
[Chorus]
Single button, cuff of truncal wall,
one clean snip frees the pair of ostia both,
Six weeks or sooner, don't let it stall,
Spiral steer wide, no kink, no coax.
Patch it, plumb it, protect the node,
Right vent opens on the avascular road,
Single button, six-week code —
sing it back so the graft never blows.
[Outro]
Single button, six-week clock,
Spiral steer around the block,
Protect the node, size the shunt,
Type Two repaired — that's the front.
