[Verse 1]
Twenty-two q eleven point two deletion strikes
Chromosome missing, cardiac chaos ignites
DiGeorge syndrome whispers truncus tales
When genes abandon ship, the heart system fails
Conotruncal malformations cluster tight
Thymus absent, parathyroids take flight
[Chorus]
PVR assessment, resistance we measure
Homografts versus synthetics, surgical treasure
PPVR criteria, percutaneous gate
Transition models navigate adult fate
Neurodevelopment hangs in the balance
Ross procedure demands surgical talents
[Verse 2]
Pulmonary vascular resistance calculations
Catheterization reveals circulation stations
Wood units climbing past the danger zone
Four units signals transplant's time has grown
Reversibility testing with vasodilators
Separates the candidates from spectators
[Chorus]
PVR assessment, resistance we measure
Homografts versus synthetics, surgical treasure
PPVR criteria, percutaneous gate
Transition models navigate adult fate
Neurodevelopment hangs in the balance
Ross procedure demands surgical talents
[Bridge]
Homografts calcify slower but degenerate fast
Synthetic conduits promise decades to last
Melody valve criteria twenty-two millimeters wide
Severe regurgitation cannot hide
Executive function suffers under bypass time
Hypothermic arrest steals cognitive rhyme
[Verse 3]
Adult congenital centers specialize care
Transition protocols handle transfer with flair
Fourteen to eighteen the critical window
Pediatric safety nets begin to winnow
Ross procedure swaps the valves around
Aortic root replacement, circulation rebound
[Outro]
From chromosome gaps to surgical art
Advanced knowledge protects every heart
Complex pathways intertwined
Clinical mastery, precisely designed
