title: Cardiac papillary fibroelastoma mimicking left atrial appendage thrombus.
abstract: A 76-year-old woman was admitted with suggested cardioembolism. Transesophageal echocardiogram revealed a large, highly mobile mass within a dynamic left atrial appendage that was confirmed by computed tomography to be prolapsing into the body of the left atrium. A multilobulated, pedunculated fibroelastoma was resected at surgery.
