[Differential diagnosis of late stages of mitral valve stenosis in the aspect of its surgical treatment].

The results of the examination and treatment of 200 patients with the IV and V stages of mitral stenosis were analyzed. Certain major criteria of differential diagnosis of the IV and V stages of the defect were established. Surgical methods for the treatment of patients of the both groups were chosen. The authors consider the most characteristic features of the IV stage to be the following: functions and structure of parenchymatous organs, microcirculation, tissue metabolism. The surgical correction of the defect by the closed and open methods is believed to be possible. Patients with the IV stage of mitral stenosis have profound disturbances of the function and structure of internal organs, microcirculation and tissue metabolism. Correction of the V stage of the defect should be performed only by the closed method.
