Abstract
A 70-year-old man with a recent history of high degree AV block presented to the hospital with progressive shortness of breath and dyspnea of exertion. A mobile intracardiac mass was found on transthoracic echocardiogram that was not present in his previous evaluations. Real time three-dimensional (3D) transesophageal echocardiography (TEE) images revealed a spherical mass within the right atrium; no enhancement after microbubble contrast infusion was noted. Modern echocardiography including 3D TEE and echocardiographic contrast perfusion imaging provide numerous advantages for non-invasive evaluation of intracardiac masses.
