BACKGROUND: Mitral valve (MV) repair is the gold standard for the treatment of @entity339 . Recently, minimally invasive mitral valve surgery (MIMVS) has shown excellent postoperative outcomes compared with conventional surgery. The aim of our study is to report early and long-term outcomes of @entity1 undergoing MIMVS through right mini-thoracotomy (RT) over an eight year period. METHODS: From September 2003 to December 2011, a total of 1,604 consecutive @entity1 underwent MIMVS through RT. RESULTS: The mean age was 62  13 years, 295 (42%) @entity1 were female and 16 (2.3%) had previous cardiac operations. MV repair was successfully performed in 670 @entity1 , with a rate of success of 95.3%. Repair techniques included annuloplasty (89%), leaflet resection (n=54.2%), neochordae implantation (12.1%), and sliding plasty (10.5%). Overall in-hospital mortality was 0.1%. Incidence of @entity64 was 1.3%. At eight-year follow-up, overall survival was 90.1%, freedom from reoperation 93%, and freedom from recurrent @entity339 was 90%. CONCLUSIONS: @entity71038 repair through right minithoracotomy is a safe and reproducible procedure associated with high rate of MV repair, and excellent early postoperative and long-term results.
