[Assessment of right ventricular function in patients with congenital heart defects with pulmonary hypertension. The role of some parameters of hemodynamics].
Intracardiac hemodynamics was studied in 46 patients with intraventricular septal defect and 32 patients with incomplete atrioventricular canal. The study confirmed practical value of assessment of contractility of right ventricular myocardium basing on information obtained during prolonged catheterization of the right cardiac chambers, construction of right ventricular function curves and analysis of pressure-volume loops. Compared with conventional hemodynamic monitoring this approach to analysis of intracardiac hemodynamics provided real time assessment of cardiac function, facilitated elucidation of causes of lowering of cardiac output and elaboration of optimal pathways of regulation of the myocardial contractile state.
