Hemodynamic analysis on prolonged survival cases (30 days and 20 days) of artificial total heart replacement

High output AH pumping causes a marked decrease in hematocrit, as well as peripheral circulatory insufficiency. By the application of a new control method, based on our hypothesis of regulating the output of the pump, maintenance of normal outputs, long term survival, after total heart replacement, has improved from 10 days to 37 days, with the average survival of 18 days. In addition, the experimentsl animals' general condition has been markeldy improved.
