Excellent short- and long-term outcomes after concomitant aortic valve replacement and coronary artery bypass grafting performed by surgeons in training

No previous studies have specifically addressed the effect of training on outcomes after concomitant aortic valve replacement and coronary artery bypass grafting. This study evaluated the early and late outcomes after concomitant aortic valve replacement and coronary artery bypass grafting performed by surgeons in training. Methods: A retrospective analysis of data collected prospectively by the Australian and New Zealand Society of Cardiac and Thoracic Surgeons Cardiac Surgery Database between June 2001 and December 2009 was performed. Concomitant aortic valve replacement and coronary artery bypass grafting was performed in 2540 patients; of these procedures, 290 (11.4 ) were by trainees. Patient demographics, intraoperative characteristics, and early morbidity were compared between trainee and staff cases using chi-square analysis and t tests. Multivariate analyses were used to determine the independent association of training status with 30-day and late mortality. Results: Compared with staff cases, trainee cases were younger (mean age, 73.0 vs 74.2 years; P ? .025) and less likely to present with triple vessel disease (27.9 vs 38.3 , P?.001) or previous cardiac surgery (6.3 vs 2.8 , P ? .016). Trainee cases had longer mean perfusion (160.4 vs 144.6 minutes, P
