Repeat coronary artery bypass grafting.
In 1981-1989 we performed repeat coronary artery bypass grafting on 42 men and 10 women (mean age 55 years) with angina pectoris recurring on average 27 months after the primary operation. The cause was occlusion or stenosis of vein grafts alone (59%) or in combination with progression of native coronary atherosclerosis (31%) or progression in the native circulation without graft failure (10%). Complications at the repeat operation included five lesions of the right ventricle and five lesions of patient grafts. The 30-day mortality was 3.8% (95% confidence limits 0.5-13.2%). Survival after observation averaging 2 1/2 years was 92.3% (95% confidence limits 81.5-97.9%). Angina pectoris was completely relieved after the operation in 48% of the patients, lessened in 35% and unchanged in 17%. Although repeat coronary artery bypass grafting carries heightened mortality and morbidity, and the results are less satisfactory than after first-time bypass, the operation can be worthwhile.
