Aorto-left ventricular continuity destruction due to prosthetic valve endocarditis is rare, but it is one of the fatal complications after aortic root operation. We report a case of surgical treatment for prosthetic valve endocarditis after aortic root replacement. A 47-year-old man, who had undergone aortic root replacement with a composite graft was transferred to our hospital with sudden chest pain and high fever. Enhanced computed tomography showed a large space with contrast enhancement suggesting perivalvular leakage around the artificial composite graft. Emergency operation including aortic root re-replacement and reconstruction of the left ventricular outflow tract was performed successfully. We focused on its technical aspect.
人工瓣膜心内膜炎导致的主动脉-左心室连续性破坏较为罕见，但它是主动脉根部手术后的致命并发症之一。我们报告一例主动脉根部置换术后人工瓣膜心内膜炎的外科治疗病例。一名47岁男性，曾接受复合移植物主动脉根部置换术，因突发胸痛和高热转入我院。增强计算机断层扫描显示一个大的有对比增强的区域，提示人工复合移植物周围存在瓣周漏。成功实施了包括主动脉根部再次置换和左心室流出道重建在内的急诊手术。我们重点关注了其技术方面。
