The auricle of the left atrium is the most superior structure within the chamber. It is a blind-ending saccule that is in continuity with the anterior wall of the chamber. Its inner surface is lined by musculi pectinati.

On the external surface of the heart, the left atrial auricle projects anteriorly and then to the right over the external surface of the pulmonary trunk.

The left auricle is longer, narrower and more angulated than its counterpart in the right atrium.
