[Assisted circulation for volume relief of the right heart ventricle].

The model of the failure of the right ventricle was formed in dog experiments. The animals were connected with the right mechanically assisted circulation. The blood was pumped synchronously with the heart action from the right atrium directly to the pulmonary artery by temporary bypass of the right ventricle. The right volume relief improved (p less than 0.03) the decisive hemodynamic parameters. The value of assisted circulation in case of the hitherto only difficulty to controlled failure of the right ventricle is proved with that.

[Comparison of the effect of catecholamines on the blood flow in the coronary and in the femoral circulation].

The effect of adrenaline and noradrenalin on the coronary circulation was studied in narcotized dogs. In 14 dogs every 20 seconds the venous blood from coronary sinus was examined. In a second series of animals the blood flow in the coronary artery and in the femoral artery was recorded continuously after intraarterial, resp. intravenous injection of catecholamines. In some experiments a constant perfusion pressure in coronary and femoral systems was maintained by help of a stabilizing device. The results of these experiments unequivocally proved that application of catecholamine was always followed by dilatation of the myocardiac and constriction of femoral vascular system. In no case catecholamines caused initial vasoconstriction of coronary vessels. The reasons for that paradoxical efficacy are discussed.
