[Method of increasing the effectiveness of assisted circulation]

The effect of venoaortal and atrioaortal auxiliary circulation (AC) on myocardial contractility of the left and right ventricles was examined in patients with acute heart failure following cardiac surgery. The atrioaortal AC technique proved to be more effective. A short-time warming of the blood from 37 degrees to 39 degrees C enhances the favourable effect of auxiliary circulation on myocardial contractility.
