Percutaneous device closure of the left atrial appendage (LAA) has been introduced in the last decade as a minimally invasive alternative treatment to long-term anticoagulation to reduce the risk of thrombo-embolism in patients with atrial fibrillation. Echocardiography is an essential tool at all stages of the procedure. Pre-procedural echocardiography is used to screen suitable candidates and to define LAA morphology and dimension; peri-procedural transoesophageal or intracardiac echocardiography has a major role in guiding, delivery, and deployment of the device, for screening of procedural complications and for assessing procedural success; and post-procedural echocardiography is important in the surveillance and monitoring of long-term outcome. This article aims to outline the role of echocardiography at each stage of LAA occlusion.
经皮左心耳（LAA）封堵术在过去十年中被引入，作为长期抗凝治疗的微创替代疗法，以降低房颤患者血栓栓塞的风险。超声心动图在该手术的各个阶段都是必不可少的工具。术前超声心动图用于筛选合适的患者，并确定左心耳的形态和尺寸；术中经食管或心内超声心动图在指导、输送和植入器械、筛查手术并发症以及评估手术成功率方面发挥着重要作用；术后超声心动图对于长期疗效的监测和随访很重要。本文旨在概述超声心动图在左心耳封堵术各阶段的作用。
