超声心动图在非瓣膜性心房颤动患者经皮左心耳封堵术中的应用进展

目前,经皮左心耳封堵术被推荐用于高卒中风险、不能耐受长期抗凝治疗的非瓣膜性心房颤动患者的卒中预防。经胸超声心动图和经食管超声心动图不仅在经皮左心耳封堵术前患者的筛选、左心耳形态和大小的观测,以及术中封堵器选择和置入过程的实时监控中发挥重要作用,同时还有利于术后封堵器位置和心功能的评估,其中经食管超声心动图已经成为经皮左心耳封堵术必不可少的术中影像学监控手段。本文就超声心动图在非瓣膜性心房颤动患者经皮左心耳封堵术中的应用进展进行综述。

Application progress of echocardiography in percutaneous left atrial appendage occlusion in patients with nonvalvular atrial fibrillation

Percutaneous left occlusion has been recommended for stroke prevention in patients with nonvalvular heart disease atrial fibrillation who are at high risk of stroke and cannot tolerate long-term anticoagulation therapy.Transthoracic and transesophageal echocardiography not only play an important role in patients selection before percutaneous left atrial appendage occlusion,the shape and size observation on the left atrial appendage,intraoperative occluder selection and real-time monitoring during the placement processing,but also facilitate the evaluation on postoperative occluder location and cardiac function.Transesophageal echocardiography has become an indispensable intraoperative imaging monitoring method.This paper reviews the application progress of echocardiography in percutaneous left auricular occlusion in patients with nonvalvular atrial fibrillation.
