Abstract

The original valve-sparing procedures for aortic root aneurysms were remodeling and reimplantation of the aortic root. The remodeling technique provides more physiologic movement of the cusps within 3 reconstructed neo-sinuses, thus preserving root expansibility through the interleaflet triangles. However, the durability of remodeling has been a matter of concern due to the high rate of aortic insufficiency when annular dilation is not addressed. Therefore, a modified approach was developed, combining a physiologic remodeling of the root with a subvalvular annuloplasty. This case report highlights the first case of successful aortic root remodeling with external subvalvular ring annuloplasty in Korea.
