Between March, 1989, and August, 1993, 10 patients underwent aortocoronary bypass surgery concomittant with cardiac valve replacement. They were 6 men and 4 women, the age ranging from 47 to 64.
7 patients underwent single valve replacement and 2 patients underwent double valve replacement, another one patient underwent only CABG one year after valve replaceent and he had no evidence of prosthetic valve failure. Total number of graft
vessels
were 15, 14 were saphenous venous grafts and 1 was internal mammary artery graft.
Dyspnea on exertion was frequent symptom and was found in all patients. 8 patients presented stable angina, only 1 patient presented postinfarct angina and another 1 patient presented no angina symptom. The grafts were placed prior to valve
replacement
and periods of myocardial ischemia were kept at a minimum by maintaining coronary perfusion throughout operation.
Postoperative course was unevenful and there was no hospital mortality. As was supported by many reports, it is our opinion that simultaneous valve replacement and aortocoronary bypass graft does not increase the risk of cardiac valve replacement
substantally. (Korean J Thoracic Cardiovas Surg 1994; 27:187-90)
