Diagnostic workup at the outside facility included a transesophageal echocardiogram that demonstrated a left ventricular ejection fraction of 55% to 60%, an 8 mm mobile mass in the left ventricle (Fig. 1a), and a competent mitral valve with no evidence of regurgitation or stenosis. Pathologic examination of the resected mass was consistent with a papillary fibroelastoma (Fig. 1b-d).
