Transesophageal echocardiography-guided transvenous endomyocardial biopsy used to diagnose primary cardiac angiosarcoma

Primary cardiac tumors are rare clinical entities with the histologic diagnosis usually made from surgically obtained tissue or at postmortem examination. Transvenous endomyocardial biopsy has been used less frequently, under fluoroscopic or transthoracic echocardiographic guidance. In this case report, we utilized the transesophageal echocardiography to guide the endomyocardial biopsy from a right atrial tumor in a 35-year-old man. (C) 1996 Wiley-Liss, Inc.
