Case description

The left atrial appendage (LAA) is the most common site for cardiac thrombus. The left atrial appendage is anatomically attached to the left inferior portion of the left atrium and consists of muscular trabeculae. The left atrial appendage does not contribute to a large degree to overall cardiac output. A left atrial appendage thrombus is diagnosed on transesophageal echocardiography as thoracic views are not adequate to visualize the left atrial appendage. Transesophageal echocardiographic findings of a left atrial appendage thrombus includes direct visualization of a mobile echodensity within the appendage. The echodensity should move independent of the walls of the atrium which helps to distinguish artifact or trabeculae from thrombus.
