概述

经导管主动脉瓣置换术(Transcatheter Aortic Valve Replacement,TAVR)是一种微创瓣膜置换手术,是通过介入导管技术,将人工心脏瓣膜输送至主动脉瓣位置,从而完成人工瓣膜植入,恢复瓣膜功能。 适应症1. 老年重度主动脉瓣钙化性狭窄(无论是否合并关闭不全),或者关闭不全。2. 患者有症状,如心悸、胸痛、晕厥、心功能Ⅱ级以上。3. 因合并多种疾病不适合开胸手术,或者开胸手术风险太大的患者。4. 主动脉根部的解剖条件适合TAVR。包括瓣膜钙化程度、主动脉

Surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR) are the mainstays of treatment of severe calcific aortic stenosis (AS), as they improve symptoms and prolong survival. For patients with severe calcific native aortic valve stenosis (AS) with an indication for valve replacement, intervention options include surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI, also known as transcatheter aortic valve replacement or TAVR). A multidisciplinary team approach is recommended in approaching patients with severe AS, as the decisions involved here are complex.     For patients with asymptomatic severe AS with an indication for valve replacement (eg, presence of LV ejection fraction (LVEF) <50 percent, very severe AS, or fall in systemic blood pressure with exercise), the choice of SAVR versus TAVR is based upon an individualized risk-benefit assessment including the estimated surgical risk (with intermediate or higher estimated surgical risk favoring TAVR and low estimated surgical risk favoring SAVR) and estimated risk of complications with TAVR (with feasibility of transfemoral TAVR and absence of high risk anatomic features favoring TAVR). There is limited evidence comparing SAVR versus TAVR in asymptomatic patients as these patients were excluded from most of the supporting trials.

手术主动脉瓣置换术(SAVR)和经导管主动脉瓣置换术(TAVR)是治疗严重钙化性主动脉瓣狭窄(AS)的主要方法,因为它们可改善症状并延长生存期。对于具有瓣膜置换的严重钙化天然主动脉瓣狭窄(AS)的患者,干预选项包括手术主动脉瓣置换术(SAVR)或经导管主动脉瓣植入术(TAVI,也称为经导管主动脉瓣置换术或TAVR)。建议采用多学科团队方法来接近严重AS患者,因为这里涉及的决策很复杂。对于无症状的严重AS且有瓣膜置换指征的患者(例如,LV射血分数(LVEF)<50%,AS非常严重,或运动时全身血压下降),SAVR与TAVR的选择基于个体化风险 - 效益评估,包括估计的手术风险(具有中等或更高的估计手术风险,有利于TAVR和低估计手术风险,有利于SAVR)和TAVR并发症的估计风险(经股TAVR的可行性和缺乏高风险解剖学特征有利于TAVR)。在无症状患者中比较SAVR与TAVR的证据有限,因为这些患者被排除在大多数支持性试验之外。
