Study design:
Between June 2010 and December 2016, 241 patients underwent an isolated
mitral valve (MV) surgery in our center. Patients who had active
endocarditis and/or MV stenosis were excluded. Propensity-score matching
for 10 baseline characteristics was used (Tab 1). 128 patients were
identified and classified into two groups; MV repair group (MVRe) and MV
replacement group (MVRp), with 64 patients in each group respectively.
The median follow-up was 5.5 years (0.003-9.101) after surgery. The
Indication of surgery was moderate to severe MVR, and we classified the
MV pathology based on the Carpentier classification (Cc).
