目的本研究旨在探讨经导管主动脉瓣植入术（TAVI）中瓣膜-患者不匹配（PPM）的中期血流动力学和临床影响。方法对165例TAVI患者在术前、出院前和术后6个月进行超声心动图和临床评估。PPM定义为有效瓣口面积指数
Objectives This study examined the mid-term hemodynamic and clinical impact of prosthesis-patient mismatch (PPM) in patients undergoing transcatheter aortic valve implantation (TAVI) with balloon-expandable valves.Background PPM can be observed after aortic valve surgery. However, little is known about the incidence of PPM in patients undergoing TAVI.Methods Echocardiography and clinical assessment were performed in 165 patients at baseline, before hospital discharge, and at 6 months after TAVI. PPM was defined as an indexed effective orifice area
