[Verse 1] Where the aortic valve should be Sits a valve that's made uniquely Two or three or four leaflets there Most commonly three we declare Never designed for double duty It may leak or narrow truly Even if it works at birth Time will show its lessened worth [Chorus] Truncal valve, truncal valve Where the aorta should resolve Two three four leaflets in the way Neo-aortic it will stay Leaky stenotic or both combined Degeneration over time Remember this for life ahead It determines what lies ahead [Verse 2] Because it wasn't meant to split Into two valves that properly fit Regurgitant flow may appear Or stenosis we should fear Leaflets that are abnormal grown Cannot function like our own Acceptable at birth it seems But long-term it haunts our dreams [Chorus] Truncal valve, truncal valve Where the aorta should resolve Two three four leaflets in the way Neo-aortic it will stay Leaky stenotic or both combined Degeneration over time Remember this for life ahead It determines what lies ahead [Bridge] After repair is complete This valve makes circulation meet Neo-aortic is its name Systemic flow is now its game Long-term behavior tells the tale Will future surgery prevail The only valve for systemic flow Its fate determines what we'll know [Chorus] Truncal valve, truncal valve Where the aorta should resolve Two three four leaflets in the way Neo-aortic it will stay Leaky stenotic or both combined Degeneration over time Remember this for life ahead It determines surgery ahead [Outro] Truncal valve determines fate Aortic surgery we may wait Neo-aortic standing lone Time will tell what it has grown
