Abstract
Percutaneous occlusion of left atrial appendage (LAA) with specifically designed devices has been proposed for those patients with AF who are ineligible for or non-compliant with anticoagulation therapy.The left atrial appendage has a complex and extremely variable structure with a multi-lobulated configuration.Because the size of occlusion device is strictly dependent on the size and shape of LAA, understanding this complex anatomy has become of paramount relevance for interventionalists involved in percutaneous occlusion of the LAA.Three-dimensional TEE provides a 3D data set of LAA which can be cut and analyzed from a countless number of planes. Additionally, each plane can be observed from multiple perspectives, allowing a more precise assessment of the anatomy of the LAA. Furthermore, a long segment of catheter can be visualized in a single image and the tip of the catheter can be tracked during the procedure. In this chapter we describe the 3D TEE anatomy of the LAA and its role in percutaneous closure of LAA.
