The frequency of minimally invasive mitral valve (MV) surgery has increased over the last decade. Hence, the number of patients requiring MV reoperations post-minimally invasive MV surgery is increasing. This study analyzed the outcomes of patients undergoing MV reoperation after previous minimally invasive MV surgery during a twenty-year period in a high volume heart valve center. A total of 187 patients were included in the analysis (34 [18.2 percent] patients repeat MV repair; 153 [81.8 percent] MV replacement). Redo MV surgery was performed through median sternotomy in 169 (90.4 percent) patients. The median intensive care unit stay was 1 day (1-5 days). The thirty-day mortality was 6.4 percent, and actuarial survival at 5 and 12 years was 61.8 percent and 38.3 percent, respectively. Endocarditis and preoperative stroke were identified as predictors of late mortality.
