Cardiac Papillary Fibroelastoma: A Treatable Cause of Transient Ischemic Attack and Ischemic Stroke Detected by Transesophageal Echocardiography

Transesophageal echocardiography (TEE) is used frequently in patients with cerebrovascular ischemia. On TEE, a typical appearance of a cardiac flbroelastoma is that of a pedunculated, mobile mass attached to a leaflet of a valve. Surgical excision of the lesion may lead to resolution of the symptoms and prevent further cerebrovascular ischemic events; valve replacement is seldom necessary. Herein we describe three patients with cerebral or ocular ischemia in whom histologic study confirmed a cardiac papillary tibroelastoma after initial detection by TEE. Cardiac papillary fibroelastomas should be considered in the differential diagnosis of transient ischemic attack and stroke, even in cases of recurrent events in the same vascular distribution. Although the use of echocardiography in the evaluation of stroke and transient ischemic attack is controversial, TEE must be considered in patients in whom the cause of cerebrovascular ischemia is unclear after noninvasive neurovascular studies or transthoracic echocardiography, even if the patient's cardiac history and the findings on physical examination are normal.
