Ultrasound cardiography showed severe aortic regurgitation (AR) due to bicuspid aortic valve with dilatation of the aortic annulus and sinotubular junction in a 27-year-old man hospitalized with loss of consciousness. He underwent aortic valvuloplasty combined with external suture annuloplasty using an expanded polytetrafluoroethylene (ePTFE) suture. Intraoperative findings revealed thickening and adhesion of the aortic root despite the first surgery. He developed recurrent AR 7 months later and underwent redo surgery. An ePTFE suture was found inside the aorta. Aortic root replacement with a mechanical composite graft was performed, as reconstruction appeared difficult because the aortic annulus was damaged and there were multiple holes on all cusps. Here, we report a rare case of aortic root destruction after external suture annuloplasty.
超声心动图显示,一名 27 岁男性因二叶式主动脉瓣导致严重主动脉瓣反流(AR),主动脉瓣环和窦管交界处扩张,该患者因意识丧失住院。他接受了主动脉瓣成形术,并结合使用膨体聚四氟乙烯(ePTFE)缝线进行了外部缝线环成形术。尽管进行了第一次手术,但术中发现主动脉根部仍有增厚和粘连。7 个月后他再次出现 AR,并接受了再次手术。在主动脉内发现了 ePTFE 缝线。由于主动脉瓣环受损且所有瓣叶上均有多个孔,重建似乎很困难,因此进行了机械复合移植物的主动脉根部置换。在此,我们报告了一例罕见的外部缝线环成形术后主动脉根部破坏的病例。
