[Radiocardiographic evaluation of the hemodynamic effect of mitral commissurotomy at different stages of the postoperative period].

The analysis of hemodynamic effect of closed mitral commissurotomy in 73 patients it different postoperative terms is presented. Within the first day after operation a dramatic hyperfunction of the myocardium was observed in patients with the 3d stage of blood circulation disorders. In patients with the 4th stage of the disease mitral commissurotomy failed to give a positive hemodynamic effect both within the first day and at later terms. In the late postoperative period there were no substantial differences between the data of central hemodynamics and postoperative data independent of the stage of the blood circulation disturbance.
