and importance: For treatment of prosthetic valve endocarditis (PVE), redo-aortic valve replacement (AVR) is usually required. However, the recurrence of PVE continues to be a serious problem that needs a solution.
An 83-year-old woman who had undergone AVR for aortic infective endocarditis 12 years ago was diagnosed with PVE complicated with acute cerebral infarction. Urgent redo-AVR was performed. After complete removal of the prosthesis, Perceval S valve was implanted successfully. There were no postoperative neurological deteriorations, and the echocardiogram showed no recurrence of PVE.
Theoretically, the fewer prostheses left in the heart, the lower the risk of PVE recurrence.
In patients with PVE, redo-AVR using the Perceval valve may be a suitable option since Perceval reduces the prosthesis in the heart compared with conventional redo-AVR.
及重要性：对于人工瓣膜心内膜炎（PVE）的治疗，通常需要再次进行主动脉瓣置换术（AVR）。然而，PVE的复发仍然是一个需要解决的严重问题。
一名83岁女性，12年前因主动脉感染性心内膜炎接受了AVR，被诊断为PVE并伴有急性脑梗死。紧急进行了再次AVR。在完全移除假体后，成功植入了Perceval S瓣膜。术后无神经功能恶化，超声心动图显示PVE无复发。
从理论上讲，心脏中残留的假体越少，PVE复发的风险就越低。
对于PVE患者，使用Perceval瓣膜进行再次AVR可能是一个合适的选择，因为与传统的再次AVR相比，Perceval减少了心脏中的假体。
