Rapid Development of a Papillary Fibroelastoma with Associated Thrombus: The Role of Transthoracic and Transesophageal Echocardiography

Transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) are frequently utilized in patient's with suspected cerebral vascular ischemia. We describe a patient with suspected cerebral vascular ischemic event whom was found to have a mobile valvular mass by TTE and TEE. The lesion was unusual due to its rapid development over a period 6 months, which was documented on serial echocardiography. The mass was excised surgically and pathology showed a papillary fibroelastoma with extensive thrombus. The differential diagnosis of a cardiac valvular mass and the treatment of cardiac fibroelastomas are reviewed. In this case, both TTE and TEE were valuable in diagnosis and facilitating surgical management of a cardiac fibroelastoma.
