[Verse 1]
First we open up the chest with sternotomy
Cut the breastbone straight to see the heart clearly
Hook up the bypass machine to take control
Blood flows through circuits while the heart stays still
[Verse 2]
Remove the thymus gland to clear the way
Study the anatomy before we operate today
See the spiral pattern of the PA course
Left branch anterior, right posterior force
[Chorus]
Step by step we reconstruct
Separate, repair, redirect
Close the holes with pericardial patches strong
Guide the blood flow where it belongs
Type Two truncus needs precision and care
Build two pathways from the single vessel there
[Verse 3]
Detach each PA branch from its own door
Two separate ostia like we've seen before
Carefully dissect and free each artery
Leaving holes in the truncal wall to see
[Verse 4]
Patch those holes with treated pericardium
Glutaraldehyde makes it strong and durable
Now the truncus serves as neo-aorta alone
A single pipe to call the left heart's home
[Chorus]
Step by step we reconstruct
Separate, repair, redirect
Close the holes with pericardial patches strong
Guide the blood flow where it belongs
Type Two truncus needs precision and care
Build two pathways from the single vessel there
[Bridge]
Right ventriculotomy opens up the wall
Avoid the coronary vessels, plan it all
Through the incision place the VSD patch tight
Left ventricle to truncus, that's the aortic flight
[Outro]
Right ventricle blood needs its own way out
Through the conduit, there's no doubt
Two circuits working as they should
Truncus repair done right and good
