In the period between July 1980 and June 1989,172 consecutive patients were submitted to combined coronary and valvular surgery. There were patients with predominantly valvular indications and others with predominant coronary indications. In 95 cases, myocardial revascularization and surgical treatment of the aortic valve (RAo) were simultaneously performed. Seventy five patients were submitted to myocardial revascularization and surgical treatment of the mitral valve (RMi). The more frequent valvular lesions were aortic stenosis (44 cases) and mitral insufficiency (40 cases). The mean number of anastomoses per patient was 1,87 for RMi cases and 1,56 for RAo patients. Overall hospital mortality was 9,8%; RAo mortality was 7,3% and RMi mortality was 12%. Mortality of patients with ischemic mitral insufficiency operated on electively (20%) or in an emergency basis (37,5%) was not statistically significant (x²=04423). There was not a relationship between mortality and the number of anastomoses per patient. A tendency for better results regarding mortality was observed in RMi patients in which the valve was preserved (x²=1,6382). The survival actuarial curves in 19 semesters demonstrates a valve of 82,6% for RMi patients, 90,4% for RAo patients and 86,3% for the whole series. After evolution of 5172 months/patients, 75% were in functional class I (NYHA).
