Fifteen-year experience with minimally invasive approach for reoperations involving the mitral valve

摘要: Objective Reoperative sternotomy to address mitral valve pathology carries substantial risk, especially with patent bypass grafts or an aortic prosthesis. We previously reported our early experience minimally invasive right thoracotomy and peripheral cannulation as alternative strategy, we recently reviewed cumulative 15-year hospital outcomes this approach. Methods Between June 1996 April 2010, performed minithoracotomy for reoperations involving the on 167 patients, 85 (51%) of these since 2006. Seventy-one percent had undergone previous coronary artery grafting 38% a previous procedure. Fibrillatory arrest was used in 77% clamping root cardioplegia 23%. Nineteen procedures were robotic assistance. Results Mitral repair frequency increased during each 5-year interval (1996–2000, 43%; 2001–2005, 53%; 2006–2010, 72%; P  = .019), including 80% native valves without stenosis. Concomitant procedure frequency, most commonly atrial fibrillation ablation, also (0%, 21%, 48%;  = .037) only independent predictor mortality multivariable analysis. Conclusions Our updated confirmed effectiveness to treat while avoiding reoperative risk. found fibrillatory cardioplegic methods be safe myocardial preservation strategies
