The elephant trunk: a rare morphology of the left atrial appendage-a case report.

ABSTRACT:

Background

Patients with atrial fibrillation (AF) are at increased risk for thromboembolic events including stroke. The primary source for thromboembolism in these patients is thrombus formation in the left atrial appendage (LAA). Depending on the individual thromboembolic risk, long-term anticoagulation is recommended. In certain patients, however, long-term anticoagulation is contraindicated, and interventional closure of the LAA (LAAC) represents an alternative approach to lower the thromboembolic risk and avoid oral anticoagulation.

Case summary

An 83-year-old male underwent LAAC at our centre in November 2022. Prior to the procedure, a thrombus in the left atrium (LA) or LAA was excluded by transoesophageal echocardiography (TOE), and the anatomy of the LAA was assessed
