Left ventricular to aortic composite conduits provide a viable surgical option for aortic stenosis patients with severe aortic calcification that precludes traditional cross clamping.
May offer bailout for calcified aortas precluding AVR; hypothesis-generating and requires validation before practice consideration.
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.
