Abstract
The extraanatomic bypass procedures from the left ventricle to the descending thoracic aorta using the valved conduits graft were performed in the experimental animal with supravalvular and subvalvular aortic stenosis. The effect of Apico-Aortic Bypass procedure on the left ventricular fuction, coronary blood flow and oxygen consumption was compared between in the suprava lvular stenotic group and subvalvular stenotic group. These Procedures provided significant decrease of the left ventricular loading in the both supravalvular, and subvalvular stenotic groups. However, Apico-Aortic Bypass significantly increased the coronary blood flow in the subvalvular stenotic group, and on the contrary, decreased the coronary blood flow in the supravalvular stenotic group.
