RVSP calculation is used for which condition?

• A. Pulmonary hypertension
• B. TV regurgitation
• C. Aortic stenosis
• D. Mitral valve prolapse

Answer: (B)

RVSP calculation is used to estimate systolic pulmonary artery pressure, which is what we’re assessing when evaluating pulmonary hypertension. The measurement comes from the velocity of the tricuspid regurgitation jet, using the Bernoulli equation and adding an estimate of right atrial pressure: RVSP ≈ 4 × (TR jet velocity)² + RAP. The presence of tricuspid regurgitation provides the signal needed to make this estimate, but the clinical purpose is to gauge pulmonary artery pressures and diagnose pulmonary hypertension. Left-sided valve issues like aortic stenosis or mitral valve prolapse are not assessed with this measurement, and while the tricuspid regurgitation signal is essential for the calculation itself, the condition being evaluated is pulmonary hypertension.
