The reimplantation technique is one of the most popular valve-sparing procedures. Previously published in-vitro studies have demonstrated the success of the aortic interleaflets triangle reshaping approach in increasing the coaptation surface. An alternative positioning of the pledgeted stitches used in the proximal suture line of the David operation is proposed to simultaneously stabilize the annulus and improve the valve functional reserve in case of annulo-aortic ectasia due to dilation of the interleaflet triangles.
瓣膜再植技术是最常用的保留瓣膜手术之一。此前发表的体外研究已证明主动脉瓣叶间三角重塑方法在增加瓣叶对合面积方面取得了成功。本文提出了一种在David手术近端缝合线中使用带垫片缝线的替代定位方法,以便在瓣叶间三角扩张导致瓣环-主动脉扩张的情况下,同时稳定瓣环并改善瓣膜功能储备。
