This study investigates tricuspid regurgitation (TR) in pulmonary arterial hypertension (PAH), assessing its impact on right ventricular (RV) function and prognosis. Among 92 PAH patients, severe TR was linked to poor survival and correlated with markers of RV dysfunction. Haemodynamic simulations suggested that tricuspid valve repair could worsen outcomes in PAH patients with low RV contractility. Effective arterial elastance (Ea) and effective pulmonary arterial elastance (Epa) were better predictors of RV dysfunction than traditional indices. These findings underscore the complex relationship between TR, RV function, and prognosis in PAH, cautioning against routine tricuspid valve repair.
