Abstract
Trans-esophageal echocardiography (TEE) revealed a left atrial appendage (LAA) thrombus in an 84-year-old woman with nonvalvular atrial fibrillation not known before our evaluation. In her medical history, there were hypertension, dyslipidemia and a previous pulmonary embolism. She was taking warfarin at time of our evaluation and presented signs and symptoms of heart failure. Together with heart failure treatment, intravenous anticoagulation with unfractionated heparin was initiated. Treatment was complicated by additional right lower limb embolic event and the LAA thrombus remained unchanged. Testing revealed heterozygosity for both the factor V Leiden and the methylenetetrahydrofolate reductase C677T mutations inducing resistance to activated protein C. The patient refused transcatheter closure of the left atrial appendage.
