PULMONARY ARTERY BALLOON PUMPING WITH SYNCHRONIZED BLOOD FLOW ASSIST FOR THE TREATMENT OF ACUTE RIGHT VENTRICULAR FAILURE -EXPERIMENTAL STUDY-

Abstract

Cardiac function and hemodynamics were evaluated in ten dogs with right ventricular infarction assisted by PABP alone (Group II) or PABP with synchronized blood flow (Group III). In group II, PABP decreased CVP, RA pres. and RVEDP significantly and also aortic flow, RV max dp/dt and RV mp were increased. But these parameters didn't return to control values. In group III, each parameter improved remarkably and return to almost control value. Therfore, PABP with synchronized blood flow assist significantly improve acute right ventricular failure (followed by improvement of left ventricular function) and could be effective for severe right ventricular failure.
