Hemorrhage and associated fistula formation in a left atrial myxoma causing coronary artery steal syndrome.

ABSTRACT

A 59-year-old woman with episodes of chest pain was diagnosed with cardiac myxoma. Transesophageal echocardiography (TEE) showed a massive vascularized tumor and there was a blood stream spurting from the internal cavity of tumor into left atrium through an interconnected sinus tract. Coronary artery angiography (CAG) indicated that the mass was enhanced upon the administration of contrast media, which spouted into the cardiac chamber. This is the first case to report the development of the coronary artery steal syndrome due to hemorrhage and associated fistula formation in a left atrial myxoma, which was detected by TEE and confirmed by CAG.
