title: [Preoperative clinical and hemodynamic characteristics of patients with mitral valve defects subjected to valve prosthesis].
abstract: Sixty one patients were studied that were subjected to mitral valvular prosthesis--28 patients with pure or prevailing mitral stenosis, 12 with pure or prevailing mitral insufficiency and 21 patients with degree competitive stenosis and insufficiency. The patients, to have mitral valvular prosthesis, undergo the operation, most often, in the presence of pronounced pulmonary capillary and arterial hypertension and preserved right-ventricular and left-ventricular function. The pulmonary hypertension is with the highest values in the patients with mitral stenosis leading. In the patients with leading stenosis, passes of compromised right-ventricular function could be established. The cases with disturbed left-ventricular function are from the groups with prevailing mitral insufficiency or competitive stenosis and insufficiency. The time for mitral valvular prosthesis should be selected so as not to allow the manifestation of bilateral cardiac insufficiency as well as the formation of essential pulmonary disorders.
