Should Moderate Functional Tricuspid Regurgitation Be Repaired During Surgery for Rheumatic Mitral Valve Disease?

Background: Surgical repair of concomitant functional moderate tricuspid valve (TV) regurgitation at the time of mitral valve (MV) surgery remains controversial.

Aim: The objective of this study was to evaluate the outcomes of concomitant repair of functional moderate tricuspid regurgitation (TR) during MV surgery for rheumatic valve disease.

Method: From 1998 to 2016, 1,240 patients had rheumatic MV disease associated with moderate functional TR: 974 patients had MV surgery and concomitant TV repair (group 1) and 266 patients had MV surgery alone (group 2).
