Abstract

Modification of 1-atrio and 1-ventricular---aortic bypass (Combination bypass): In our original methode of combination bypass, 2 inflow ducts were independently connected to the 1 atrium and the 1 ventricle respectively. These ducts were adherered together in one duct, and inserted through the 1 auricle, though their inflowing way were separated by septum. On hemodynamic effects by pumping, total left heart bypass and the complete unloading of the 1 ventricle were constantly obtained.
