Propensity-matched analysis of minimally invasive mitral valve repair using a nationwide surgical database

摘要: The aim of this study was to compare the cases minimally invasive mitral valve surgery (MICS-mitral) performed using right mini-thoracotomy (RT) with those median sternotomy (MS). Between 2008 and 2012, 6137 patients underwent isolated repair at 210 institutions were registered in Japan Adult Cardiovascular Surgery Database. We compared 756 who MICS-mitral via RT 5381 MS a one-to-one matched analysis based on estimated propensity score. in-hospital mortality similar between both groups (RT vs. MS: 0.5 1.1 %). Although incidence postoperative stroke, renal failure, prolonged ventilation similar, number mediastinitis greater group 0 0.7 %, p < 0.01). Reexploration for bleeding more frequent 2.9 1.4 %, Mortality morbidity occurred higher rate low-volume institutions. showed that operation-related times significantly longer group, while length hospital stay shorter. In <60 years age, there no mortality. successful without compromising clinical outcomes. operation time should be improved, an approach is safe appropriately selected patients, especially age or treated high-volume center.
