title: [Method of surgical treatment of mitral valve stenosis depending on the extent of its calcinosis].
abstract: On the basis of studying the immediate and long-term results of treatment of 329 patients with calcinated mitral stenosis, the progressive aggravation of the immediate outcome of the operation in II and III-IV degree of mitral valve calcinosis is demonstrated. The data have been confirmed by actuarial analysis of the patients' survival and stability of a good result. The authors consider it expedient to perform mitral commissurotomy only in patients without valvular calcinosis and I degree calcinosis. In more severe affection, mitral valve replacement is indicated.
