摘　　要：瓣周漏(PVL)是经导管主动脉瓣置换术(TAVR)的常见并发症,TAVR术后的发生率远高于外科主动脉瓣置换术。最近的报告表明,PVL可能与晚期死亡率的增加有关,这引起了关注。然而,评估和量化PVL方法的异质性,使发生率及严重程度分级也各不相同。现通过综合目前文献分析,对TAVR术后瓣周漏的评估、发生机制及处理方法做一综述。Perivalvular leakage(PVL)is a common complication of transcatheter aortic valve replacement(TAVR)and the incidence of PVL after TAVR is much higher than that after traditional surgical aortic valve replacement.Recent reports suggest that PVL may be associated with an increase in late mortality.However,the grading of incidence and severity varies due to the heterogeneity of methods for assessing and quantifying PVL.Currently,the evaluation,occurrence mechanism,and treatment of paravalvular leakage after TAVR are summarized by a comprehensive literature analysis.
