Abstract

A 16 year-old Korean girl with cardiomegaly was found to have a "right atrial cystic mass" on transthoracic echocardiography. An unusual cystic structure made the diagnosis difficult. However, transesophageal echocardiography and multidetector computed tomography revealed a coronary artery fistula with a distal saccular aneurysm involving the interatrial septum and draining into the right atrium. Multidetector computed tomo-graphy provided clear anatomic visualization that fully delineated the abnormal structures. Multidetector computed tomography may be considered as a good alternative for transesophageal echocardiography in assessing a tortuous coronary artery fistula and aneurysm with complex anatomy.
