Abstract: Total of 123 patients (mean age: 63.8 +/- 7.3 years, (male/female 65/35 percent) underwent mitral valve surgery combined with coronary artery bypass grafting during a seven year period. Preoperatively 12% of them belonged to NYHA functional class II, 54% to class III, 29% to class IV and 3% was operated under emergency conditions. The mitral valve lesion was most frequently either ischaemic (45%) or rheumatic (33%) in origin. Left ventricle function was moderately decreased in 18% and severely damaged in 3% of the patients as documented by preoperative ventriculography. Coronary surgery was performed in all cases with an average number of distal anastomosis of 2.2 +/- 1.1 per patient. The hospital mortality was 13%. Risk factors for early and late mortality were determined by univariate and multivariate analysis. Advanced preoperative functional class and decreased left ventricular function or ischaemic etiology were identified as significant risk factors for early mortality. The patients were followed for an average of 33 +/- 25 months. The majority of them experienced significant functional improvement postoperatively with 69% belonging to NYHA class I or II. The late survival for the 107 hospital survivors was 94.7% at one year, and 84.7% at five years, respectively. Late survival was independently determined by preoperative functional class or previous myocardial infarction. Freedom from ischemic and valve related complications at five years was 95% and 71.2% respectively. 58.2% of the hospital survivors were in functional class I or II and free of any valve related or ischemic complications at the end of the fifth follow up year.(ABSTRACT TRUNCATED AT 250 WORDS)
