Background: The aim of this study was to analyze the results of the re-operative coronary artery bypass surgery(Redo CABG). Methods: Thirty three redo CABGs from January 2001 to July 2008 were analyzed retrospectively. Mean age was 62.6 짹 9.0 years with a range of 41 - 75 years and twenty five patients (75.8%) were men. Mean interval from primary CABG was 100.1 짹 67.3 months and mean left ventricle ejection fraction (LVEF) was 52 짹 12.5% (26 – 78%). Pre-operative risk factors included 2 cardiogenic shocks, 7 chronic renal failures, and 5 ischemic cardiomyopathies (LVEF ��� 35%). Redo CABGs included 18 conventional CABG, 7 on-pump beating heart CABG, 6 off-pump CABG, and 2 minimally invasive direct coronary artery bypass (MIDCAB). Mean number of distal anastomosis was 2.8 짹 0.9. Associated procedures included 1 mitral annuloplasty, 1 tricuspid annuloplasty, 1 atrial septal defect closure, 1 mitral valve replacement, and 1 aortic valve replacement. Results: No hospital deaths and 1 late death occurred. Post-operative complications included 5 low cardiac output syndromes, 5 atrial fibrillations, and 3 neurologic complications. Conclusions: In the current era, redo CABG is nearly as safe as the primary operation.
