A 72-year-old man who underwent a left atrial appendage (LAA) closure device 2 years ago presented with atrial flutter with rapid ventricular rate and was referred for cardioversion. Precardioversion transesophageal echocardiogram showed left atrial thrombus and therefore the procedure was aborted. Currently, there is no guideline on imaging surveillance or anticoagulation in patients with LAA closure device who develop intracardiac thrombus after the initial 6-month surveillance period.
