[Venoarterial perfusion without oxygenation as a means of mechanical aid to the heart in acute failure].

The efficacy of veno-arterial perfusion without oxygenation was established in experiments on dogs with a model of acute cardiac insufficiency. The overall index of circulation and the percentage of the heart participation in it is an important criterion of the effectiveness of shunting of the left ventricle. This criterion made it possible to determine the therapeutic role of veno-arterial perfusion without oxygenation in aiding the diseased ventricle even when the size of the shunt did not exceed 1/3 of the initial cardiac ejection.
