[Radiocardiographic assessment of hemodynamics in different types of acquired heart valve defects].
The hemodynamic disorders in various types of cardiac defects were studied in 133 subjects, 82 of them patients with aquired combined valvular defects of the heat and the results obtained were juxtaposed. The hemodynamics was determined by the method of quantitative radiocardiography (QRCG). The volume of circulating blood was determined as well as the indices of cardiac output, ventricular, pulmonary quantities and the indices of aortic route. The results obtained by the numerous indices followed up, juxtaposed to the separate defects, reveal hemodynamic disorders, manifested to various degrees in the various heart defects. The hemodynamic disorders in two-axis heart defects (mitral and aortic) proved to be most severe. Stroke and minute volumes were diminished. The time for filling of the right and left heart was twice prolonged. The rate of pulmonary and systematic hemodynamics was retarded two and a half times. Better manifested hemodynamic disorders advance in mitral stenosis as compared with mitral insufficient. The hemodynamic disorders in combined aortic defects proved to be the lightest.
