Left ventricle descending aorta valved conduit to relieve congenital aortic stenosis in children.
A valved conduit was inserted between the apex of the left ventricle and the descending aorta in 2 patients, 4 months and 10 years of age, respectively, who had valvular aortic stenosis. The development of both patients has been excellent since operation. At control catheterization (1 and 2 years postoperatively) no pressure gradient was found between the left ventricle and the aorta. In both patients the aortic valve area showed growth to near normal size on echocardiographic study 3 years postoperatively.
