Between September 1986 and August 1996, 233 patients (187 males, 46 females) ranging in age from 32 to 81 (mean 54.7) years received at least one internal mammary artery (IMA) graft for coronary artery bypass procedures. The mean left ventricular ejection fraction was 55.1% (range, 17 to 75%). An average of 3.1 distal anastomoses per patient was constructed. Hospital mortality was 2.1%. Perioperative myocardial infraction was seen in 2.1%. The mean follow-up of hospital survivors was 39.2 (range, 4 to 123) months. Ten-year actuarial survival for patients discharged from the hospital was 96%. Recurrence of angina occurred in 18 patients and reoperation or PTCA was performed in 3 patients in the late follow-up period. These results support the continuing use of IMA grafts for myocardial revascularization.
