Abstract

The absence of sinuses of Valsalva is postulated to perturb coronary flow patterns and to create abnormal leaflet stresses, which theoretically may limit the long-term durability of valve-sparing aortic root replacement with the original Tirone David-I reimplantation technique with a cylindrical tube graft. David developed the "T. David-V" procedure in 2001; it creates large billowing Dacron pseudosinuses while retaining the reimplantation concept. To illustrate a simple modification of the T. David-V technique, we describe a patient with Marfan's syndrome who underwent valve-sparing aortic root replacement with 1 large and 1 small graft to create pseudosinuses in the Dacron graft, to facilitate suturing the valve inside the graft, and to make the distal graft-to-aorta anastomosis a better size match.

摘要

据推测,无瓦尔萨尔瓦窦会扰乱冠状动脉血流模式并产生异常的瓣叶应力,从理论上讲,这可能会限制采用原始蒂罗内·大卫 - I法使用圆柱形人工血管进行保留瓣膜主动脉根部置换术的长期耐久性。大卫在2001年开发了“T. 大卫 - V”手术;该手术在保留再植入概念的同时,形成了大的涤纶假窦。为了说明对T. 大卫 - V技术的一种简单改良,我们描述了一名患有马凡综合征的患者,该患者接受了保留瓣膜主动脉根部置换术,使用了1个大的和1个小的人工血管,以在涤纶人工血管中形成假窦,便于将瓣膜缝合在人工血管内,并使远端人工血管与主动脉的吻合口尺寸匹配更佳。
