JACC:TAVR术的容积-结果关系研究

2019-02-12 MedSci MedSci原创

目前,关于经导管主动脉瓣置换术(TAVR)中的容积-结果关系(VOR)尚存在争议。本研究的目的旨在评估在初始学习曲线(LC)后,球囊扩张式(BE)TAVR的VOR是否存在,且LC和VOR是否随着设备的不同而不同。本研究纳入了TVT数据库中的61949名BE-TAVR患者,主要终点事件包括30天全因死亡率、卒中和主要血管并发症。分析结果发现,在所有商业用途的BE瓣膜中,LC大概在第201例病例时结束

目前,关于经导管主动脉瓣置换术(TAVR)中的容积-结果关系(VOR)尚存在争议。本研究的目的旨在评估在初始学习曲线(LC)后,球囊扩张式(BE)TAVR的VOR是否存在,且LC和VOR是否随着设备的不同而不同。

本研究纳入了TVT数据库中的61949名BE-TAVR患者,主要终点事件包括30天全因死亡率、卒中和主要血管并发症。分析结果发现,在所有商业用途的BE瓣膜中,LC大概在第201例病例时结束,在LC结束后,VOR关系不明显。在S3瓣膜中,LC和VOR均不明显。

研究结果显示,在经过200例初始学习过程后,经导管主动脉瓣置换术中的容积-结果关系不明显,在最新一代瓣膜中,LC和VOR均不明显。
