[Verse 1]
When conduits narrow and pressures spike high
RV at ninety while systemic's seventy-five
The balloon catheter threads through the vein
Into right chambers where stenosis brings pain
Inflate and stretch, fracture the block
Watch those numbers drop around the clock
[Chorus]
Four pathways forward when the conduit fails
Balloon, stent, valve, or surgical trails
From ninety down to forty-six
Subsystemic pressure fix
Twenty gradient left behind
Palliation by design
[Verse 2]
Metallic scaffolds hold the space wide
Stents within conduits, durable guide
Re-dilate as bodies grow tall
More lasting than balloons that fall
Steel framework keeps the pathway clear
Buying precious months and years
[Chorus]
Four pathways forward when the conduit fails
Balloon, stent, valve, or surgical trails
From ninety down to forty-six
Subsystemic pressure fix
Twenty gradient left behind
Palliation by design
[Verse 3]
Melody SAPIEN through the skin
Transcatheter valves placed within
Sixteen millimeters minimum zone
Twelve won't fit, needs room to grow
Pre-stented landing, catheter-based
Open surgery can be displaced
[Bridge]
When interventions reach their end
Surgical replacement we depend
Remove the old, install the new
Sized for current body's due
Multiple times throughout a life
Definitive beneath the knife
[Chorus]
Four pathways forward when the conduit fails
Balloon, stent, valve, or surgical trails
From ninety down to forty-six
Subsystemic pressure fix
Twenty gradient left behind
Palliation by design
[Outro]
At ten months old the balloon saves
Pressure gradients misbehave
Each option buys another phase
In truncus arteriosus maze
