title: Aortic stenosis complicated by severe calcification of the wall of the ascending and transverse aorta: management by use of left ventricular to aortic composite conduit. Report of two cases.
abstract: The use of left ventricular aortic composite conduits in 2 patients with severe intramural calcification of both the ascending and the transverse aorta is reported. This method is felt to be superior to conventional aortic valve replacement, when the texture of the aortic wall does not allow cross clamping or secure closure.
