A review of 507 off-pump coronary bypass patients: a single center experience

This retrospective study evaluates perioperative results of 'Off-pump' coronary artery bypass surgery (OPCAB) experience in a single center. Five hundred and seven patients were operated (median sternotomy) from 1998 to 2002 using OPCAB. Patient data were registered and risk prediction calculated using the full logistic version of EuroSCORE. Overall, 1091 distal anastomoses were performed and only five (1%) patients required conversion to cardiopulmonary bypass. The predicted mortality was 3.8+/-4.5%, the observed mortality was 2.37%. OPCAB technique has become a standard approach in our department with low mortality and morbidity rates even in treatment of multivessel disease or high-risk patients.
