The value of coronary angiography in the work-up of atrial myxomas

Abstract

Atrial myxomas are the most common primary cardiac tumors. They are highly vascular with evidence of neovascularization and a characteristic"tumor blush" in approximately half of the cases. Although the visualization of feeding vessels has several clinical and therapeutic implications, there is still no consensus on the indication of preoperative coronary angiography to assess tumor vascularity except in patients with angina or those older than 40 years to rule out coronary artery disease. Herein, I present a case of an incidentally discovered right atrial mass receiving vascular supply from the right coronary artery. The mass was successfully excised and the diagnosis of cardiac myxoma was confirmed via histopathology. A review of the value of coronary angiography in detecting myxoma neovascularization is provided, which suggests that it can offer additional valuable information that can alter the surgical approach and therefore may be considered prior to myxoma resection.
