Abstract/OtherAbstract:
|
Outer aortic wall morphology and thickness were compared in the Hancock porcine aortic bioprosthesis and the Carpentier-Edwards porcine aortic bioprosthesis. The overall average aortic wall thickness, the average maximum thickness, the average minimum thickness, and the average variation in aortic wall thickness were greater in the Hancock valve. Differences in preparation technique accounted for the disparities. The tunica adventitia and variable amounts of the outer tunica media were generally removed during processing of the Carpentier-Edwards valve prior to mounting in the stent. The removal of this tissue at times exposed to deeper collagenous cusp anchor at the commissures. Possible implications of these differences are briefly considered. |
