A 38-year-old man experienced a transient ischemic attack and underwent transthoracic echocardiography. Left ventricular systolic function and wall motion were normal. A broad-based hyperechoic mobile mass was found on the apicolateral wall (A and B, Online Videos 1 and 2). Magnetic resonance imaging of the heart revealed a 2-cm pedunculated mass with intermediate signal intensity on T1-weighted images (C). At thoracotomy, the mass was gelatinous and yellow in color. Microscopy was consistent with a papillary fibroelastoma (D and E).
Papillary fibroelastomas are the third most common benign cardiac neoplasia that typically occur in the atrioventricular valves (1). They arise rarely in the cardiac chambers, where they can present with peripheral embolization.
