摘　　要：目前,经导管主动脉瓣置换术(TAVR)已成为有症状的严重主动脉瓣狭窄(AS)和中、高外科手术风险患者的一种收益较高的治疗选择。在重度AS患者同时合并主动脉瓣小瓣环(SAA)时,其独特的主动脉根部解剖特征增加了手术的挑战性,患者的治疗策略的选择成为了近年来备受关注的热点话题。以往研究表明,此类患者行TAVR表现出更好的血流动力学特征和预后。本文主要对重度AS患者SAA患病率、人群特征及超声心动图在SAA患者行TAVR术前主动脉根部情况的评估中的应用进行综述。Currently,transcatheter aortic valve replacement(TAVR)has emerged AS a high-yield treatment option for symptomatic patients with severe aortic stenosis(AS)and moderate-to-high surgical risk.In patients with severe AS and concomitant small aortic annulus(SAA),its unique aortic root anatomical characteristics increase the challenge of surgery,and the choice of treatment strategy has become a hot topic in recent years.Previous studies have shown that such patients show better hemodynamic characteristics and prognosis after TAVR.This article mainly reviews the prevalence and population characteristics of SAA in patients with severe AS,and the application of echocardiography in the evaluation of aortic root condition before TAVR in SAA patients.
