The use of minimally invasive mitral valve surgery (MIMVS) has increased in recent years, and surgeons are seeing more patients requiring reoperation after MIMVS. This study analyzed early outcomes and long-term survival in this group. A total of 187 patients were included, with 18 percent undergoing repeat mitral valve (MV) repair and 82 percent undergoing MV replacement. Redo mitral valve surgery (MVS) was completed via median sternotomy in 90 percent of cases. Thirty-day mortality was 6.4 percent. Estimated five and twelve year survival were 62 percent and 38 percent, respectively. Preoperative stroke and infective endocarditis were independent predictors of long-term mortality. The research found that redo MVS can be performed safely in this group, yielding low early mortality and acceptable long-term survival rates.
