BACKGROUND
Prosthetic valve endocarditis (PVE) is a serious complication, and it is difficult to treat marked adhesion and infectious tissue.
CASE PRESENTATION
There were four patients with aortic PVE, whose ages ranged from 59 to 80 years. In all patients, transoesophageal echocardiography revealed periannular abscess formation. We applied aortic annular enlargement techniques using a composite three-layer patch to repair the defects after radical debridement of the abscesses, and then replaced the prosthetic valves on the reconstructed annuli. All patients received antibiotics after surgery and recovered well without recurrence.
CONCLUSIONS
The aortic annular enlargement techniques provided a good field of vision at the complicated annulus, and our original patch was useful for repairing the aortic annulus and its surrounding apparatus.
背景
人工瓣膜心内膜炎（PVE）是一种严重的并发症，且其感染组织与瓣膜的黏附十分顽固，难以治疗。
病例介绍
共有 4 名主动脉瓣 PVE 患者，年龄 59 岁至 80 岁。所有患者的经胸超声心动图均显示瓣周脓肿形成。我们采用复合三层补片扩大主动脉瓣环技术，在彻底清除脓肿后对脓肿进行清创，然后在重建的瓣环上更换人工瓣膜。所有患者术后均接受抗生素治疗，恢复良好，无复发。
结论
主动脉瓣环扩大技术为复杂瓣环提供了良好的视野，我们原创的补片对于修复主动脉瓣环及其周围结构非常有用。
