E-page Original Images: Giant left atrial myxoma with dual blood supply accompanying significant coronary artery stenosis

A 69-year-old woman presented to our institution with palpitation and fatigue, which had started one month ago. She had no prior history of cardiac disease. On admission, her arterial blood pressure was 100/70 mmHg; pulse rate was 138 bpm/irregular. On physical examinati- on there was a systolic murmur with a grade of 1/6 on the apex of heart. Chest radiography revealed a hypodense area on the right border of sternum (Fig. 1). Electrocardiography showed atrial fibrillation with rapid ventricular response. Transthoracic echocardiographic examina- tion detected a hyperechoic, globular, large mass occupying almost the entire the left atrium (Fig. 2). Subsequent transesophageal echocardiog- ram confirmed the presence of a huge mass (7.6 x 5.1 cm) within the left atrium (Fig. 3). Mass was partly cystic and attached to the fossa ovalis part of interatrial septum.
