Role of Intracardiac Echography for Transcatheter Occlusion of Left Atrial Appendage.

Left atrial appendage closure (LAAC) is an increasingly common procedure for patients with nonvalvular atrial fibrillation and contraindications to long-term anticoagulation. Traditionally, LAAC has been performed under transesophageal echocardiography (TEE) guidance. Although most operators have become experienced and comfortable with TEE-guided appendage closure, there has been a growing interest in the use of intracardiac echocardiography (ICE) for LAAC. This article describes the rationale and technique for ICE-guided LAAC.
