Abstract

Nonpulsatile biventricular bypass during chronic ventricular fibrillation. Chronic nonpulsatile blood flow was established in 4 animals, ranging from 34 to 93 days. Two centrifugal type nonpulsatile pumps were used to bypass both ventricles which were kept fibrillated during the entire course of experiments. After acute responses during the first 7 to 10 days postoperatively, hemodynamics returned to normal and afterwards all organ function was maintained within normal ranges, provided adequate flow and pressure were maintained. Therefore, nonpulsatile blood flow is not a limitation for animal's survival.
