Transcatheter Left Atrial Appendage Closure Using Intracardiac Echocardiographic Guidance From the Left Atrium

摘要

Background: Most commonly, left atrial appendage (LAA) occlusion procedures are performed using transesophageal echocardiography (TEE) guidance and general anaesthesia. Intracardiac echocardiography (ICE) offers potential advantages over TEE, however, ICE-guided LAA occlusion experience is limited and has been typically performed from a right-sided location where LAA visualization might be suboptimal. We sought to evaluate the efficacy and safety of percutaneous LAA occlusion using ICE guidance performed from the left atrium.
