[Effect of mitral valve calcinosis on the remote results of commissurotomy].
The results of 249 mitral commissurotomies in calcification of the mitral valve are analysed. The authors have differentiated three grades of calcification of the valve and two groups according to its functional state. Late results were followed up in 177 patients within the terms up to 10 years and longer. The persistant positive result was noted in 99 patients, in 11 cases it was regarded as poor, and in 37--unstable. Postoperatively 34 patients died. The analysis enabled the authors to state that the positive effect of closed mitral commissurotomy could be also gained in considerable calcification. Prosthetic replacement of the valve is indicated in the presence of massive calcinosis associated with the rigidity of cusps and marked regurgitation.
