Left ventricular (LV) false aneurysm is an uncommon complication of myocardial infarction. Conventional treatment mandates surgical repair but is associated with significant perioperative risk. We present a case of successful percutaneous closure of a LV false aneurysm in a patient at high operative risk who suffered cardioembolic stroke related to thrombus within the aneurysm. The primary aim of treatment was to prevent recurrent embolic event.
