Aortic valve sparing operations

Abstract

Aortic valve sparing operations were developed to preserve the aortic valve in patients with ascending aortic aneurysm and aortic insufficiency or patients with aortic root aneurysm. There are 2 types of aortic valve sparing operations, remodeling of the aortic root and reimplantation of the aortic valve. The author believes that remodeling of the aortic root is more appropriate for older patients with ascending aortic aneurysm, dilated aortic sinuses, and normal aortic annulus, whereas reimplantation of the aortic valve is more appropriate for young patients with aortic root aneurysm in whom dilation of the aortic annulus is commonly associated. Although remodeling of the aortic root has been extensively used in patients with aortic root aneurysm, the long-term results are somewhat inferior to reimplantation in most series. The late results of aortic valve sparing operations have been excellent, and these operations have become an important addition to the surgical armamentarium to treat patients with proximal aortic aneurysms.
