[Verse 1] Picture the right ventricle pressed inside a clamp, Conduit gone narrow, stenosis sets the ramp, Muscle thickens concentric, walls stacking like a fort, Chasing two-thirds systemic, pressure storms the court, Cross that line, the subendocardium starts to starve, Coronary flow gets clipped on the systolic arc, High pressure chokes the vessels running through the wall, Deepest fibers go hungry while the outer layers stall, This is pressure overload, the silent architect of strain, Thickened muscle can't outwork the climbing, choking pain. [Chorus] Squeeze thick, that's concentric strain, Two-thirds systemic knocking on the gate, Stretch wide, that's the volume chain, Septum bows left, interdependence straight, Mixed road rattles both loads in one frame, Stiff RV whispers restriction's name, Five signs, one muscle — learn the right ventricle's game. [Verse 2] Now flip the lesion, conduit's a leaky gate, Pulmonary regurgitation floods the freight, Chamber stretches, end-diastolic volume grows, Annulus widens till the tricuspid overflows, Functional TR rides the stretching tide, Volume overload — a slow ballooning slide, No thickened wall here, just a chamber running wide, Blood sloshing backward with every failing stride. [Chorus] Squeeze thick, that's concentric strain, Two-thirds systemic knocking on the gate, Stretch wide, that's the volume chain, Septum bows left, interdependence straight, Mixed road rattles both loads in one frame, Stiff RV whispers restriction's name, Five signs, one muscle — learn the right ventricle's game. [Verse 3] Two chambers share a wall, that's interdependence's law, Dilated, pressurized RV makes the septum fall, Bows leftward, flattens, steals the LV's room, Filling drops, ejection fraction dims too soon, Low LVEF — a guideline's warning flare, Marks the heart for outcomes surgeons must prepare, Now mix the lesion: stenotic and regurgitant in one, Pressure climbs the ladder while the volume floods the run, Stenosis caps the backflow, limits how far it goes, But the RV still grinds under two loads it can't disclose. [Bridge] Stiff right ventricle, rigid, noncompliant drum, Atrial kick drives flow when diastole goes numb, Antegrade pulse in the PA, late in the beat, A paradox that guards against the regurgitant feat, Less backward volume, almost looks like grace, But it's diastolic dysfunction wearing a borrowed face. [Chorus] Squeeze thick, that's concentric strain, Two-thirds systemic knocking on the gate, Stretch wide, that's the volume chain, Septum bows left, interdependence straight, Mixed road rattles both loads in one frame, Stiff RV whispers restriction's name, Five signs, one muscle — learn the right ventricle's game. [Outro] Pressure, volume, septum, mix, and stiff decree, Five roads loading on one chamber's symmetry, Know the strain before you choose the knife, That's how the conduit buys the ventricle more life.
