经导管主动脉瓣置换术后瓣周漏相关危险因素研究进展

Risk Factors Related to Perivalvular Leakage After Transcatheter Aortic Valve Replacement

经导管主动脉瓣置换术(TAVR)目前已成为主动脉瓣狭窄患者的主要治疗方式之一,瓣周漏(PVL)是TAVR术后的常见并发症之一,轻度PVL可以影响患者的远期生存率,中、重度PVL是TAVR术后死亡率的独立预测因素。明确PVL的相关危险因素,可以较大程度上避免严重PVL的发生,改善TAVR术后患者的远期预后,现主要介绍PVL相关危险因素的研究进展。

Transcatheter aortic valve replacement(TAVR)has become one of the main treatment options for patients with aortic stenosis.Perivalvular leakage(PVL)is a common complication after TAVR,and mild PVL can affect the long-term survival of patients,while moderate to severe PVL is an independent predictor of mortality after TAVR.Identifying the relevant risk factors for PVL can greatly reduce the occurrence of severe PVL and improve the long-term prognosis of patients after TAVR.This article mainly introduces the research progress on the risk factors related to PVL.
