Abstract
The newly developed electromechanical left ventricular assist device was characterized in failing heart dogs. The left renal arterial and left common carotid arterial blood flowa were measured by electromagnetic flow probe to evaluate the peripheral circulation. Authors observed that 2L/min LV-Ao bypass flow improved the circulatory condition and 1-2ml/Kg/hr of urinary output was maintained. This bypass flow was equal to 75% of the normal cardiac output. So it would be good enough for the peripheral circulation if the left ventricular assist device could bypass 75% of the normal cardiac output.
