title: [Indications for and the postoperative results of mitral valve prosthesis].
abstract: The influence of 20 hemodynamic and clinical indices on the postoperative results was studied in 528 patients with mitral valve prosthetics. One year after the operation 78.7% of the patients are with improved functional capacity, 18.8% are without change and 2.5% are in worse condition. The lack of improvement correlates moderately with the postoperative complications (r = 0.4701) and to a larger degree with the number of patients in the II functional class before the operations (r = 0.7342). The deterioration of the functional capacity is in relation to the complications by operations on the tricuspid valve (r = 0.8773), but there is also considerable correlation with the low ejection fraction (r = 0.6425), previous commisurotomy (r = 0.5871) and uncorrected tricuspid valvular disease (r = 0.6314). The operative lethality rate is 6.25%.
