BACKGROUND: This retrospective study evaluates morbidity and mortality of reoperative coronary artery bypass grafting (CABG) without cardiopulmonary bypass (CPB) using a posterior thoracotomy to revascularize the lateral aspect of the heart. METHODS: From January 1995 to July 1999, reoperative CABG without CPB was performed on 67 selected patients using a left posterior thoracotomy approach. Preoperative risk factors, postoperative mortality, and major complications were derived from the New York State database. RESULTS: All patients were operated on without CPB. A total of 1.3 grafts per patient were performed. Freedom from major complications was 95.5%. There were no postoperative cerebro-vascular accidents (CVA) or new neurological deficits. Two patients (3%) had a perioperative acute myocardial infarction. The actual mortality rate was 4.5% (3/67), the expected mortality was 5.1% and the calculated risk adjusted mortality was 2.1%. CONCLUSIONS: Reoperative CABG without CPB to revascularize selected coronary artery targets can be safely performed using a posterior thoracotomy approach.
