Right Atrial Myxoma Arising from Crista Terminalis in Septuagenarian

Abstract

A right atrial myxoma arising from the crista terminalis was detected during follow-up echocardiography in a 74-year-old man who had undergone coronary artery bypass grafting one year earlier. The myxoma was excised en bloc with a wide cuff of normal atrial wall and the right atrium was reconstructed with autologous pericardium.

Intraoperative transesophageal echocardiography assessment of right atrial myxoma resulting in a change of the surgical plan

“…[6] Very rarely, it arises from Eustachian valve near inferior vena cava or the free wall of the right atrium. [7,8] In our patient, the tumor was very large and originated from cristae terminalis, the free wall of the right atrium. Because of large size, the preoperative TTE failed to localize the precise attachment of the tumor.…”
