[Hemodynamics and the heart volumes of patients before and after mitral valve prosthesis].

The article deals with a complex study of parameters of the hemodynamics and volume of the cardiac cavities in comparison with a clinical state of patients suffering from mitral defect before and in different periods following prosthesis of the mitral valve. On the basis of the results obtained during examination of 54 patients there was revealed a complete conformity between their clinical state, data of the hemodynamics, the volume of the heart and left auricle. A reverse development of many signs characteristic of the defect was established. The absence of an absolute improvement of some clinical and hemodynamic indices in remote periods following the operation in a number of patients was connected with a marked increase of the cardiac volumes before the operation, an unsatisfactory contractile capacity of the myocardium, the remaining of cardiac fibrillation after the operation.
