背景 - 本研究的目的是比较经导管主动脉瓣置换术 (TAVR) 治疗的严重主动脉瓣狭窄 (AS) 患者在有或没有假体-患者不匹配 (PPM) 的情况下使用心肌应变进行的左心室 (LV) 重塑。方法和结果 - 在一项回顾性研究中，使用散斑跟踪超声心动图测量整体纵向应变 (GLS) 和应变率 (GLSR)、周向应变以及术前和中期的旋转TAVR 后随访。中度和重度 PPM 定义为有效孔口面积
Background-The aim of this study was to compare left ventricular (LV) remodeling using myocardial strain between patients with severe aortic stenosis (AS) treated with transcatheter aortic valve replacement (TAVR) with and without prosthesis-patient mismatch (PPM).Methods and Results-In a retrospective study, speckle-tracking echocardiography was used to measure global longitudinal strain (GLS) and strain rate (GLSR), circumferential strain, and rotation before and at mid-term follow-up post-TAVR. Moderate and severe PPM were defined as an effective orifice area
