Echocardiographic Imaging for Left Atrial Appendage Occlusion: Transesophageal Echocardiography and Intracardiac Echocardiographic Imaging

Interv Cardiol Clin. 2018 Apr;7(2):219-228. doi: 10.1016/j.iccl.2018.01.001.

Abstract

Left atrial appendage occlusion (LAAO) is a rapidly evolving technology. Multi-modality imaging and understanding of left atrial appendage anatomy are sure to advance. Two-dimensional and 3-dimensional transesophageal echocardiography with fluoroscopy are the mainstay for LAAO image-guided therapy. Key to successful LAAO is an understanding of the transseptal puncture, LAAO size selection for the device-specific landing zone, and postdeployment evaluation for leak and complications. With advancements in computed tomography, there may be a greater role for intracardiac echocardiographic imaging in specific types of LAAO anatomy and devices.
