[Changes of intracardiac hemodynamics in patients with secondary atrial septal defects before and after surgery].
Investigation of the central and intracardial hemodynamics was conducted in 60 patients with secondary defects of the interatrial septum. Using the method of long cardiac catheterization it was established that the systolic pressure in the right ventricle decreased and the final diastolic pressure increased which was an indication of functional insufficiency of the ventricle. This was confirmed by the reduction of work and potency of the right ventricle. Changes in the myocardial contractility in the nearest days after the operation were accompanied by a reduction in the maximum rate of the intraventricular pressure growth in the medium rate of ejaculation.
