[Verse 1] Conduit's whistling, continuous-wave ear on the pipe, Four V-squared, Bernoulli's the hype, Simplified math, instantaneous peak, But that number alone's only half what we seek, Catheter room truth runs peak-to-peak lower, Mean gradient's the cousin that correlates slower-paced, closer, Trace the envelope, don't just eyeball the spike, Average the curve if you want the real strike. [Chorus] Mean over peak, catheter's the referee, Tubular tunnel's lying through its velocity, TR jet whispers what the conduit can't confess, Four V-squared plus RA, that's the real RVSP guess, Half-time under a hundred, PR index below point seven-seven, Branch PA flow running backward — that's your regurgitation heaven, Sing it, scan it, trust the whole array, Echo's the scout before MRI, CT, cath day. [Verse 2] Here's the trick they don't teach in the first-year slides, Long tube conduits got nowhere for the jet to hide, No discrete orifice, no clean narrow throat, Pressure recovers downstream, Doppler's overstating the quote, So that screaming gradient on your spectral display Might be echo's exaggeration, not truth on display, Cross-check with mean, cross-check with the cath, Numbers lie solo but reveal on a shared graph. [Verse 3] Flip to the tricuspid, find that regurgitant stream, It's quieter, humbler, but tells the real regime, Four V-squared on TR, add your right atrial guess, That RVSP number cuts through the mess, Conduit jet's shouting, might be echo illusion, Tricuspid's murmuring the calmer true conclusion, When conduit and TR data start to disagree, Trust the tricuspid as your compass at sea. [Chorus] Mean over peak, catheter's the referee, Tubular tunnel's lying through its velocity, TR jet whispers what the conduit can't confess, Four V-squared plus RA, that's the real RVSP guess, Half-time under a hundred, PR index below point seven-seven, Branch PA flow running backward — that's your regurgitation heaven, Sing it, scan it, trust the whole array, Echo's the scout before MRI, CT, cath day. [Bridge] Dense jet diving steep, deceleration quick and cruel, Diastole's flooding back, that's the leaky conduit's rule, Watch the right ventricle swell like a tired old drum, TAPSE dropping low says the squeeze has gone numb, Fractional area shrinking, septum flattening flat, Bowing toward the left like it's tired of that pact, LV getting squeezed by a neighbor overgrown, Every measurement's a clue, none of them stand alone. [Outro] Four V-squared opens the door, mean grad confirms the floor, TR jet settles the score, pressure half-time keeps score, Echo's just the first chapter, screening before the scan, Send it onward to MRI, cath, and the surgical plan.
