Progression of moderate TR from the baseline was similarly observed in rheumatic and degenerative populations at a median follow-up of 53 months at 1, 5 and 7 years. It was 15.6% 33.8 and 39.3% in RHD group and 16.1%, 30.4% and 36.02% in degenerative group, respectively. In contrast to mitral valve repair versus replacement plus TA, progression of moderate TR was less in the MV repair group (SHR: 1.69(1.03-2.78); P= 0.038).
