Abstract
Other valvular lesions associated with pure MS were studied in 202 consecutive patients whose mean age was 43·4±12·7 years; 76·7% were females. MS was isolated in 63·4%, associated with aortic regurgitation (AR) in 27·7%, aortic stenosis in 1·0%, tricuspid slenosis (+aortic valve lesion) in 1·0%. In isolated MS, 42·4% were NYHA class III or IV, compared with 49·0% in MS +aortic valve lesion. One hundred and sixty-nine (85·4%) patients were operated on; 23·1% had mitral valve replacement, 76·9% had closed (31·45%) or open (45·6%) mitral commissurotomy; 7·1% had associated aortic valve replacement. There were perioperative complications in 20·4%, and the perioperative death rate was 4·1%. Two patients were reoperated in the postoperative course, and 28 patients after this period. The followup was 13·3±4·5 years. The survival rate was 77·7±4·6% (SE) for irolated MS, and 71·1±6·3% for MS associated with an aortic valve lesion (NS). The prognosis of MS ir very good: the survival rate at 20 years followup is 75%. The awociation of aortic stenosis or tricuspid stenosis does not appear to alter this survival, but numbers are small. Important aortic regurgitation is a significant predictor of higher mortcllity in patients with MS.
