Abstract

Experimental studies were performed using right heart assist device for these severe right heart failure right ventricular myocardial infarction. and right heart failure which follows left heart assisted circulation.
When the right heart was assisted, pulsatile flow was more effective than nonpulsatile one.
In case of right sided failing heart, the effect of right heart assist circulation was obviously noted.
In case of heavy right heart overloading (abnormal pressure or volume loading), changes of right atrial wave was specific findings and one of determinants of indication of right heart assist circulation.
