Experimental investigations concerning the improvement of the myocardial circulation of an intraoperatively resuscitated heart






Zeitschrift fuer Experimentelle Chirurgie Transplantation und Kuenstliche Organe 18(2): 118-127

Experimental investigations concerning the improvement of the myocardial circulation of an intraoperatively resuscitated heart

A pumping system for supporting an intraoperatively heart failure is presented. This system consists of a bell-shaped receptacle for the heart and a pump with a working volume of 49 ml and a working pressure of 220 Torr. The pumping power is transmitted to the heart by means of an external pneumatic pressure line. The efficacy of the pump in the high pressure system amounted to 20-30%. An effective coronary perfusion in a case of a cardiac failure is guaranteed by a venous underpressure pump of this pumping system. A favorable influence was observed in case of the low pressure system.
