[Experimental testing of the left-ventricular and biventricular assistant systems in dogs].
The left-ventricular (LVAD) and bi-ventricular assistant system (BVAD) were tested in dogs. Our hitherto existing experiences give information specially for the indication of LVAD and BVAD. The risk of a belated application of the LVAD exists in case of only a clinical control by pressure parameters for the degree of a cardiac insufficiency caused by coronary starvations. An aortic pressure of nearly 150/70 mm Hg could be reached by means BVAD on condition of heart fibrillation and a left-atrial pressure of 20 mm Hg. The aortic pressure and the left-atrial pressure decrease drastically after disconnection of the BVAD and these attain the initial values again very promptly after a new connection with the BVAD.
