Between 1990 and 1999, 78 patients underwent combined valvular coronary artery operation. Aortic valve disease was present in 49 patients, mitral valve disease in 23 patients, aortic and mitral valve disease in 6 patients. The average age was 67 years. Twelve patients had had a previous myocardial infarction. The average number of grafts inserted was 1.82 per patients, and the average number of artery grafts inserted was 0.96 per patients. The most number of grafts were placed prior to valve replacement or plasty. And periods of myocardial ischemia were kept at a minimum by coronary perfusion through free grafts. Preoperative mortality was 1.3%. And event fee ratio after operation was 95% (mean follow up 42 month). Therefore the operative risk of combined surgery is, in general, low and the long term results are favorable.
