[Evaluation of functional state of myocardium after open-heart surgery].
The intracardiac and central hemodynamics was studied in patients with secondary atrial septal defects pre- and post-operatively. After surgery continuous catheterization of the heart chambers was employed which permitted to receive the information directly from the right ventricle. Following a statistical processing of the obtained data, regression lines were formed that reflected the relationship between the work-load of the right ventricle and the end-distolic pressure. It was demonstrated that the development of latent myocardial insufficiency requires certain limitations in the amount of the infused fluids and enhancement of cardiac therapy.
