Long-term prognosis of mild functional tricuspid regurgitation after mitral valve replacement

Abstract

Objective: Functional tricuspid regurgitation (FTR) is the most common type of tricuspid insufficiency and occurs approximately in 30% of patients with mitral valve disease. The major etiologic factor in the triggering of right ventricular dilation and thus causing functional tricuspid regurgitation, is pulmonary artery hypertension secondary to mitral valve disease. We aimed to analyze long-term outcomes of patients with mild tricuspid regurgitation at the time of mitral valve replacement.
