Predictors of in-hospital mortality following redo cardiac surgery: Single center experience.

Purpose Redo cardiac operations represent one of the main challenges in heart surgery. The purpose of the study was to analyze the predictors of in-hospital mortality in patients undergoing reoperative cardiac surgery by a single surgical team. Methods A total of 1367 patients underwent cardiac surgical procedures and prospectively entered into a computerized database. Patients were divided into 2 groups based on the reoperative cardiac surgery (n = 109) and control group (n = 1258). Uni- and multivariate logistic regression analysis were performed to evaluate the possible predictors of hospital mortality. Results Mean age was 56 ± 13, and 46% were female in redo group. In-hospital mortality was 4.6 vs. 2.2%, p = 0.11. EuroSCORE (6 vs. 3; p > 0.01), cardiopulmonary bypass time (90 vs. 71 min; p > 0.01), postoperative bleeding (450 vs. 350 ml; p > 0.01), postoperative atrial fibrillation (AF) (29 vs. 16%; p > 0.01), and inotropic support (58 vs. 31%; p = 0.001) were significantly different.
