ABSTRACT
The features of the morphology of paravalvular insufficiency (PVI) were studied on the basis of analysis of 5,113 prosthetic replacements of the heart valves. From the clinical results and noninvasive and invasive data the authors revealed the peculiarities of the disorders of hemodynamics and functional condition of patients with PVI. Information on the specific features and the results of 35 repeated operations in PVI are discussed. Analysis showed 26.4% survival among patients 5 years after surgery. Bearing in mind the severity of the complication the authors emphasize the importance of its prevention.

Diagnostic potential of clinical and noninvasive instrumental investigations was compared to that of invasive techniques in 224 cases of dilated cardiomyopathy. The results provided grounds for identification of informative diagnostic criteria of the disease applicable in wide clinical practice.

Submaximum bicycle and respiration ergometry was conducted before and after sinus rhythm recovery by means of electric impulse stimulation in 41 patients with atrial fibrillation after effective mitral commissurotomy. Physical working capacity was reduced considerably (by 25.8%), while oxygen spending per unit of work increased by 58.5% in patients with atrial fibrillations, as compared to normal subjects. After sinus rhythm was recovered, physical working capacity increased by 106%, while oxygen spending per 1 kgm work declined by 34.2%. Sinus rhythm recovery is essential as an element of postoperative rehabilitation in cardiosurgical patients.

A vast experience of over 1500 patients with prostheses of the heart valves is being summarized. A method of physical and psychological rehabilitation of these patients is described and data are given proving the efficacy of such measures: increased physical endurance in work by 92%, decrease of psychic disorders by 41.5%. The efficacy of the sanatorium stage of post-operative treatment is shown. Not infrequently the degree of invalidity of patients with cardiac valve prostheses is exaggerated, it is stressed that the use of exercise tests by the rehabilitation commission is essential.
