Conservative operation for mitral stenosis with densely fibrosed or partially calcified valves. An eight-year evaluation.

Of 284 patients undergoing open mitral commissurotomy for mitral stenosis from January 1978 to December 1985, 81 patients had a densely scarred or partly calcified valve. In this study, we evaluated the postoperative results in these 81 patients. There were no operative or late deaths. Seventy-seven patients (95%) are in Functional Class I or II. Three patients required reoperation 3, 30, and 50 months after the initial procedure because of moderate or severe residual mitral regurgitation. After valvotomy there were four episodes of embolism. The actuarial rate of freedom from any complication (mortality, reoperation, congestive heart failure, and thromboembolic events) was 89.3% +/- 3.9% (mean +/- standard error of the mean) 8 years after operation. We conclude that for a follow-up period of 8 years, the stenotic mitral valve with anatomical deformities can be salvaged with satisfactory results. Therefore, we believe that this approach, at present, is a better alternative than prosthetic replacement with any type of valve presently available.

X-ray appearance and clinical significance of left atrial wall calcification.

Ten patients with calcifications of the left atrium are reported with review of the literature. Calcification of the left atrium is frequently associated with history of rheumatic fever, longstanding congestive heart failure, atrial fibrillation, mural thrombus and embolization. Early recognition of such lesions is essential for the management of the patients, particularly when surgical intervention is contemplated. A practical classification of left atrial calcification is proposed according to the dominant lesion in each group: (a) Calcification of the left atrial appendage alone (Mitral stenosis). (b) cacification of all 3 component lesions of the left atrium, i.e., the left atrial appendage, the free wall, and the mitral valve (Severe mitral stenosis). (c) Calcification of the left atrium in MacCallum's patch alone (Mitral insufficiency).
