The left atrial appendage ( LAA ) in the setting of non‐valvular atrial fibrillation ( NVAF ) is the predominant location for intracardiac thrombus formation. An absent LAA is a very rare congenital cardiac anomaly. We present a case of a 79‐year‐old female with NVAF , high CHADS 2 VASC 2 score, and high bleeding risk who presented for elective Watchman™ left atrial appendage closure device implant. A pre‐procedural transesophageal echocardiography showed an absent LAA . This finding was confirmed with cardiac computed tomography and a left atrial angiogram. The patient was discharged on medical therapy with close outpatient follow‐up.
