BACKGROUND: Conventional reoperative coronary artery bypass grafting using cardiopulmonary bypass carries relatively high mortality and morbidity. METHODS: Seventy-seven patients underwent coronary artery bypass grafting without cardiopulmonary bypass in two centers between 1988 and 1994. Mean age was 65 +/- 8 years (mean +/- SD). Twenty-three (30%) were operated on urgently and 7 (9%) emergently. Nine (12%) were referred for operation up to 2 weeks after acute myocardial infarction. Fifteen patients (19%) had an ejection fraction less than or equal to 0.35. The mean number of grafts per patient was 1.7 (range, 1 to 3), and the internal mammary artery was used in 66 patients (86%). Only 18 patients (23%) received at least one graft to the circumflex artery. Hospital stay was 7.4 +/- 6.5 days. RESULTS: Early events included operative death in 4 patients (5.2%), nonfatal myocardial infarction in 3 (3.9%), sternal infection in 2 (2.6%), and stroke in 0 (0%). Follow-up (30 +/- 15 months) showed 11 deaths (5 cardiac, 6 noncardiac), 2 (2.8%) nonfatal myocardial infarctions, and return of angina in 9 patients (12.8%). One- and 4-year actuarial survival rates were 90% and 69%, respectively. CONCLUSIONS: Reoperative coronary artery bypass grafting without cardiopulmonary bypass has acceptable early and midterm outcome, and should be considered a viable alternative for properly selected patients.
