TAVR对于中度风险的重度主动脉瓣狭窄的患者是一种替代疗法

对于手术高风险的严重主动脉瓣狭窄的患者,经导管主动脉瓣置换(TAVR)是一种替代方法,但很少有人关注手术风险适中的主动脉瓣狭窄患者接受该疗法的风险收益。

研究人员在临床研究中招募了风险适中的重度症状性主动脉狭窄患者,比较使用TAVR疗法与主动脉瓣置换术的风险收益。试验的主要终点是患者在接受手术后24个月由任何原因导致的死亡或中风致残发生率。

研究中1660人接受了手术,平均年龄79.7岁(SD 6.2)。试验的24个月TAVR组终点发生率为12.6%,手术组为14.0%,手术组发生急性肾损伤、心房颤动和输血需求的比例较高而TAVR组发生残余主动脉瓣关闭不全与起搏器植入的比例较高。

结果显示,TAVR对于中度风险的重度主动脉瓣狭窄的患者是一种替代疗法。

Circulation:高风险和不能手术的主动脉瓣狭窄患者TAVR的长期效果

在高风险(HR)和不能手术患者的经导管主动脉瓣置换术的初始PARTNER试验中,1年时死亡率在HR患者中是24%,不能手术患者中是31%。SAPIEN3导管主动脉瓣置换系统的最近30天的成果报告显示不良事件的发生率很低,但鲜为人知的是此装置的长期结果。在2013年10月和2014年9月间,583例HR(65%)或不能手术(35%)的患者通过经股动脉(84%)或心尖/主动脉16%)手术在美国29个地

JACC:TAVR预后不良风险模型,到底有没有应用价值?

目前,研究人员已经开发了一系列模型来识别经导管主动脉瓣置换术(TAVR)后高风险患者,以帮助指导治疗选择,提供患者对长期结果的期望,并支持决策的制定。来自美国的研究人员开展了一项研究,这项研究审查了以前开发的TAVR预后不良风险模型在外部数据集的性能,并探讨了老年领域对模型性能的增量贡献。TAVR后的不良结果被定义为死亡,生活质量(QOL)较差,或QOL下降,研究人员使用堪萨斯城心肌病问卷进行调查

NEJM:中等手术风险的主动脉瓣狭窄患者是选择手术换瓣还是TAVR?

Circulation:有趣的临床疲劳量表

随着经导管主动脉瓣置换术(TAVR)的出现,其已经成为治疗主动脉瓣狭窄的高风险老年人的选择。虚弱的老年病学概念已经为心血管专业人员关心的一个主流。目前急切地需要采用一种工具来客观化虚弱的定义,并相应地辨别在具有多种慢性疾病的复杂个体中患者体质的好与坏。初步研究表明,疲劳脆弱状态是TAVR1后中期死亡率和残疾的最佳预测因素之一,这使得其被应用到临床的护理途径和预测风险模型中。小型单中心研究的结果令人
