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.
最初用于主动脉根部动脉瘤的保留瓣膜手术是主动脉根部重塑和再植入。重塑技术可使瓣叶在3个重建的新窦内有更多生理性运动,从而通过瓣叶间三角区保持根部的可扩展性。然而,由于未处理瓣环扩张时主动脉瓣关闭不全发生率较高,重塑的耐久性一直是个问题。因此,开发了一种改良方法,将根部的生理性重塑与瓣下环成形术相结合。本病例报告重点介绍了韩国首例采用外部瓣下环行瓣环成形术成功进行主动脉根部重塑的病例。
