Between November, 1984, and May, 1986, 93 patients underwent combined valvular and coronary artery operation. They were 70 male and 23 female, the age ranging from 29 to 82. From this population 89 patients underwent single valve replacement and 4 patients underwent double valve replacement. Patients with mitral valve disease were in the majority present in the age group between 50 till 70, where as in the group after 60 years, patients with aortic valve disease were dominant. The main indication for aortic valve replacement was aortic stenosis and the indication for mitral valve replacement was equal between mitral stenosis and mitral incompetence, the later was due to papillary dysfunction after myocardial infarction. Dyspnea was a very frequent symptom and it was found in nearly all patients. 28 patients had a previous myocardial infarction and severe left ventricular dysfunction. The grafts were placed prior to valve replacement and periods of myocardial ischemia were kept at a minimum by maintaining coronary perfusion throughout the operation. It is our opinion that simultaneous valve replacement and myocardial revascularization does not increase the risk of cardiac valve replacement substantially.
