A 20-year-old male undergoing mechanical aortic valve replacement suffered from prosthetic valve endocarditis by Coagulase negative Staphylococci 3 months postoperatively. Echocardiography revealed left ventricular distention, severe paravalvular leakage, valve detachment and large periannular abscess adjacent to the left main coronary artery. Redo-AVR was successfully performed with a cryopreserved aortic allograft by cylinder technique. The orifice of abscess was covered with the aortic wall of the graft. Postoperative echocardiography showed trivial central regurgitation and the abscess cavity went on vanishing. He discharged from hospital 2 months later without any symptom.
一名20岁接受机械主动脉瓣置换术的男性患者，术后3个月发生了由凝固酶阴性葡萄球菌引起的人工瓣膜心内膜炎。超声心动图显示左心室扩张、严重瓣周漏、瓣膜脱离以及左主冠状动脉旁巨大瓣周脓肿。采用带瓣主动脉同种异体移植物经圆筒技术成功进行了再次主动脉瓣置换术。脓肿开口被移植物的主动脉壁覆盖。术后超声心动图显示微量中心反流，脓肿腔持续消失。2个月后他无症状出院。
