Abstract

To the Editor.—  Several methods have been investigated for assisting the failing heart. Clauss et al have studied external counter pulsation techniques. Brown et al and Schilt and others have worked with intraaortic balloon pumping to augment cardiac output. Dennis et al, among others, have worked with the body squeezer or external counter pulsation technique in an attempt to augment cardiac output and relieve the work load of the heart. Venoarterial perfusion with membrane gas exchange has received considerable attention recently. None of the above methods has earned wide application because of their various disadvantages.We have been evaluating right ventricular balloons. When inflated they evacuate blood from the right side of the heart, displace the interventricular septum to the left, and therefore evacuate blood from the left side of the heart. In both the fibrillating animal and the fibrillating heart-lung preparation this method of cardiac assistance has produced significant
