Key result
Severe tricuspid regurgitation in patients with pulmonary arterial hypertension was associated with overestimated PASP on echocardiography, yielding 37.5% accuracy versus 62.5% with mild-moderate TR.

Severe TR may overestimate PASP on echo in PAH; leaves open whether catheterization confirmation is routinely warranted.

Does severe tricuspid regurgitation reduce the accuracy of echocardiographic pulmonary artery systolic pressure estimation in patients with pulmonary arterial hypertension?
Absolute Event Rate: 37.5% vs 62.5%
Severe tricuspid regurgitation is associated with significant overestimation of pulmonary artery systolic pressure on echocardiography compared to right heart catheterization in patients with PAH.
Özpelit et al. (2015) conducted a cohort in Pulmonary arterial hypertension (n=72). Severe tricuspid regurgitation vs. Mild-moderate tricuspid regurgitation was evaluated on Accuracy of echocardiographic PASP estimates (≤10 mmHg difference with RHC measurement). Severe tricuspid regurgitation in patients with pulmonary arterial hypertension was associated with overestimated PASP on echocardiography, yielding 37.5% accuracy versus 62.5% with mild-moderate TR.
