The hemodynamic effect of closed mitral recommissurotomy based on data from manometry in the heart chambers and from echocardiography

: The hemodynamic effect of operation was studied in 181 patients after closed mitral recommissurotomy on the basis of findings of intraoperative manometry in the heart chambers and echocardiography. Lower pulmonary hypertension was noted in 87.9% and that of the diastolic gradient on the mitral valve in 86.4% of patients operated upon. The echocardiographic parameters were considerably improved. The use of this operation for treatment of patients with recurrent mitral stenosis was proved to be possible.
