[Verse 1] When the conduit's born, the pressure's clean Twenty to thirty, that's the normal scene Right ventricle pumping to pulmonary ground But stenosis creeps without a sound The lumen shrinks, resistance grows The heart must work where blood still flows From ten millimeters down to nine The gradient climbs, a warning sign [Chorus] Pressure gradient tells the tale When stenosis starts to prevail RV climbing, fighting hard Suprasystemic danger card Sixty-seven means alarm Hypertrophy causes harm Watch the numbers, feel the squeeze Conduit stenosis brings hearts to their knees [Verse 2] Three months post-op, thirty-two's the peak Seven months later, catastrophe we seek Sixty-seven gradient, mean of thirty-seven RV pressure soaring past systemic heaven Leaflets once preserved now restrict the flow Nine point eight lumen, shrinking as we go The right side battles harder than the left Of normal circulation, it's been theft [Chorus] Pressure gradient tells the tale When stenosis starts to prevail RV climbing, fighting hard Suprasystemic danger card Sixty-seven means alarm Hypertrophy causes harm Watch the numbers, feel the squeeze Conduit stenosis brings hearts to their knees [Bridge] Post-intervention brings the numbers down Forty-eight peak, the RV's no longer drowned Moderate regurgitation trades the fight Better than failure in the night From suprasystemic back to earth Intervention proves its worth The conduit breathes, the pressure falls Echo chambers tell it all [Outro] Serial echoes track the trend Before the right ventricle meets its end Gradients climbing past the norm Signal the approaching storm
