Unusual Case of Two Synchronous Intracavitary Primary Cardiac Tumors

We report a patient who had two histologic and distinct synchronous intracardiac tumors, with one located in each atrium. The second tumor was missed on intraoperative transesophageal echocardiography, but was discovered when the right atrium was opened using a bi-atrial trans-septal approach. We discuss the merits of this approach and the role of additional imaging for cardiac tumors.
