Cardiac Tumor Within the Left Ventricle

Papillary fibroelastoma is a benign cardiac tumor that most commonly arises from the valvular endocardium and is typically resected because of its predisposition to cause embolic complications. In this clinical vignette, we describe the case of a patient who presented with a round, mobile 1.3 × 1.1-cm sessile mass attached to the left ventricular apex discovered on transthoracic echocardiography at an outside institution. A multidisciplinary team and multimodality imaging approach were taken to treat a diagnostically challenging presentation of a papillary fibroelastoma due to lack of visualization on higher-resolution imaging studies.
