Abstract :
A 61-year-old male presented for an annual exam and received a transthoracic echocardiogram (TTE) which revealed a mobile mass
arising from a subaortic membrane. Further investigations with a transesophageal echocardiogram (TEE) and cardiac computerized
tomography angiography (CTA) confirmed the presence of a mobile 9 mm × 3 mm mass on a subaortic membrane. Cardiothoracic
surgery was performed with an open operation removing the mass and subaortic membrane. Upon visual inspection, the mass was
likened to a sea anemone and immunohistochemical staining performed pathologically confirmed the diagnosis of cardiac papillary
fibroelastoma. This case represents the first reported example of a cardiac papillary fibroelastoma (PFE) arising from a subaortic
membrane. Although PFEs are benign cardiac tumors, proper identification and consideration for excision of these lesions may
be indicated to prevent thromboembolic complications.
