An increasing number of reports reveal the safety and efficacy of catheter ablation for atrial fibrillation therapy even in patients with a history of prosthetic heart valve. This case report presents a 60 year old female patient who had a prosthetic mitral paravalvular leak as a complication of radiofrequency ablation. Surgery revealed a 15 mm hole and three broken knots in the posterolateral mitral annulus. This report demonstrates radiofrequency ablation for atrial fibrillation in patients with prosthetic mitral valve may cause a paravalvular leak likely as a result of thermal injury. Moreover, patient can be asymptomatic at first. The clinician should keep in mind such complication and the patient should be evaluated in terms of paravalvular leakage.
越来越多的报告显示，即使是有心脏人工瓣膜病史的患者，导管消融治疗心房颤动也具有安全性和有效性。本病例报告介绍了一名60岁女性患者，她因射频消融术出现人工二尖瓣瓣周漏并发症。手术发现二尖瓣后外侧瓣环有一个15毫米的洞和三个断结。本报告表明，人工二尖瓣患者进行房颤射频消融可能会因热损伤导致瓣周漏。此外，患者起初可能无症状。临床医生应牢记此类并发症，应对患者进行瓣周漏评估。
