Abstract： Replacement of the aortic valve and aortic root has been the standard surgical strategy for patients with aortic root aneurysm for many years. Along with the increasing knowledge about the aortic root anatomy and physiology, and complications after aortic valve replacement, the technique of valve-sparing aortic root replacement has developed greatly. We focus on the etiology and classification aortic valve insufficiency, the valve-sparing techniques and clinical outcomes of valve-sparing aortic root replacement in this review.
