Percutaneous left atrial appendage closure is increasingly performed for stroke prevention for patients with nonvalvular atrial fibrillation with contraindications to oral anticoagulation. The success and complication rates with left atrial appendage closure have dramatically improved with maturing experience, growing procedural familiarity, and preprocedural planning. Multimodality imaging involving cardiac computer tomography angiography, transesophageal echocardiography, or intracardiac echocardiography in conjunction with fluoroscopy has improved the efficacy, procedural success, and safety of left atrial appendage closure in recent years. Proceduralists need to familiarize themselves with the various modalities and understand their complimentary roles and their limitations.
经皮左心耳封堵术越来越多地用于预防非瓣膜性心房颤动伴口服抗凝禁忌的患者发生卒中。随着经验的成熟、操作的熟悉程度和术前规划的增加，左心耳封堵术的成功率和并发症发生率显著提高。近年来，多模态影像学（包括心脏计算机断层血管造影、经食管超声心动图或心腔内超声心动图与透视相结合）提高了左心耳封堵术的疗效、手术成功率和安全性。术者需要熟悉各种方式，并了解它们的互补作用及其局限性。
