[Verse 1] At ten months old the conduit's tight RV pressure climbing way too high Ninety over seventy-five tonight The right ventricle's working overtime Through the vein we thread the wire Balloon catheter takes us higher Into the stenotic space we go Inflate and stretch, watch pressure flow [Chorus] Four ways to fix the narrow path Balloon and stent, valve, surgery's wrath From ninety down to forty-six These interventions do the tricks When conduits fail and pressures rise We have four tools to save their lives Balloon, stent, valve, or replace Each option finds its time and place [Verse 2] Post-balloon the numbers tell the tale Forty-six where ninety used to sail Subsystemic now instead of high Twenty gradient remaining, that's just fine But balloons alone won't hold for long That's where metal stents belong Wire mesh to keep the lumen wide Re-dilatable as patients grow in size [Chorus] Four ways to fix the narrow path Balloon and stent, valve, surgery's wrath From ninety down to forty-six These interventions do the tricks When conduits fail and pressures rise We have four tools to save their lives Balloon, stent, valve, or replace Each option finds its time and place [Bridge] Melody valve or SAPIEN too Transcatheter replacement, something new Sixteen millimeter landing zone Pre-stenting helps when conduits have grown But when all catheter options fade away Surgical replacement saves the day Remove the old, put in the new A lifetime journey, tried and true [Verse 3] Each intervention buys us time Palliative steps in treatment's climb From simple balloon to complex stent To valve replacement, pressure's spent And when technology can't reach the goal Surgery steps in to make them whole Multiple times throughout their years Each option calms the parents' fears [Chorus] Four ways to fix the narrow path Balloon and stent, valve, surgery's wrath From ninety down to forty-six These interventions do the tricks When conduits fail and pressures rise We have four tools to save their lives Balloon, stent, valve, or replace Each option finds its time and place [Outro] Progressive steps from least to most Each technique deserves its boast Truncus patients need them all These four options help them grow tall
