26 cases of @entity339 ( @entity339 ) were treated by combined surgery: mitral valve replacement (MVR) and coronary bypass grafting (CBG). This type of operation is not common (1.3 p. 100 of all operations) and is usually reserved for @entity1 (21 cases) of middle age (average 59 years). A half of the cases had suffered previous @entity583 ( @entity583 ), an average 5 months before surgery (range 20 days to 2 years). The other half had severe @entity951 or ECG changes of @entity296 . 23 @entity1 were in Class IV (15 @entity1 ) or Class III (8 @entity1 ) of the NYHA classification. 6 of the cases required intraaortic balloon pumping. @entity339 was severe () in half of the cases with a raised pulmonary capillary (mean V wave = 52 mmHg) and @entity551 (mean = 47 mmHg: exceeding 60 mmHg in 7 cases). The coronary lesions were severe in 18 @entity1 (12 cases of double and 6 of @entity66 including 2 cases of left main stem stenosis). @entity397 were found in 11 cases and @entity5720 in 4 cases. Surgery comprised MVR with 12 bioprostheses and 14 mechanical prostheses. 33 CBG were performed (anterior wall: 15 cases, posterior wall: 11 cases). In addition, one tricuspid annuloplasty and 3 ventricular aneurysmectomies were carried out. The hospital mortality was 15.4 p. 100. The main causes of morbidity were low output states and postoperative @entity583 (2 cases).(ABSTRACT TRUNCATED AT 250 WORDS)
