Aortic Valve-Sparing Operations

Abstract

Aortic valve-sparing operations were developed >3 decades ago and have become part of the surgical armamentarium to treat patients with aortic root and ascending aortic aneurysms. Although remodeling of the aortic root is physiologically sounder than reimplantation of the aortic valve, most surgeons seem to prefer the latter. This review summarizes the views of one of the pioneers of aortic valve-sparing operation and includes their development, the various modifications that occurred over the years, comparative outcomes with aortic root replacement with valved conduits, outcomes from several recently reported series, and the future directions. The author argues that comparisons between aortic valve-sparing operations and aortic root replacement with valved conduits based on retrospective studies are inappropriate because these 2 types of surgery are performed in patients with different aortic valve pathology. Late outcomes after aortic valve-sparing operations have not been consistent among various reports and raise the question of surgical expertise and patients' selection. Aortic valve-sparing operations are the best treatment for young patients with aortic root aneurysm and normal aortic cusps. Further studies are needed to define their role in the management of patients with diseased aortic cusps.
