Abstract

Aim of this study was to compare redo MV surgery patients undergoing right mini-thoracotomy and EAC with redo MV patients undergoing surgery through other approaches. Redo MV patients from 7 European centers were analyzed. Primary endpoint was 30-day mortality; secondary endpoints were stroke, re-exploration, low cardiac output syndrome (LCOS), respiratory failure, and intensive care unit (ICU) and in-hospital length-of-stay. Forty-nine patients underwent right mini-thoracotomy and EAC (22.7%), and 167 (77.3%) underwent surgery through other approaches (112 sternotomy, 40 unclamped mini-thoracotomies, and 15 mini-thoracotomies with trans-thoracic clamp). Thirty-day mortality, stroke, re-exploration for bleeding, and weaning failure were comparable. The EAC group showed significant lower rate of LCOS (p = 0.03) and shorter ICU (p = 0.04) and in-hospital length of stay (p = 0.002). The EAC allows the surgeon to reach the aorta, to clamp it, and to deliver the cardioplegia with a "no-touch" technique, with significant improvement in outcomes.
