Comparative Study
Coronary reoperation with and without cardiopulmonary bypass.
Redo coronary artery bypass grafting (CABG) is still associated with increased morbidity and mortality compared to primary operation. Myocardial protection is one of the key issues in redo on pump CABG and is still a matter of debate. Off pump redo CABG seems to be an attractive alternative as native coronary blood flow remains and cross clamping of the aorta is avoided. ⋯ Overall survival was 83.8% in the on pump group and 88.6% in the off pump group (p = 0.92). On pump redo CABG and off pump redo CABG can be safely performed with low mortality and morbidity. Off pump redo CABG might be limited due to incomplete revascularization.
