[Coronary artery bypass graft with internal mammary artery in 53 cases]
Coronary bypass graft (CABG) with internal mammary artery was used (IMA) in 53 cases. They were treated medically but not effective. More than one time myocardial infarctions occurred 44 cases, and 16 of them had complicated ventricular aneurysm. All of them had moderate hypothermia cardiopulmonary bypass except one, who was only subjected to anastomosis of left IMA to left anterior descending branch without cardiopulmonary bypass. The mean grafts of this group were 4.28 (lift ventricular aneurysmectomy was performed simultaneously in 4 cases). Operative death was occurred in 4 cases. Of the 35 cases which had been followed for 6 months to 1 year, 30 were free of symptoms, 5 got better and had more physical exertion. It is suggested that CABG with IMA is satisfactory.
