  Fig. 1 Transthoracic echocardiography 4-chamber view color Doppler demonstrates abnormal flow along the interatrial septum (A, arrow). Transesophageal echocardiogram bicaval view shows a defect (arrow) adjacent to the interatrial septum in the expected location of the inferior vena cava (B) with color Doppler evidence of left-to-right flow (C). Contrast-enhanced 320-multidector cardiac CT inferior 4-chamber reformat shows contrast-opacified blood in the dilated coronary sinus draining into the right atrium (D). A biatrial reformat illustrates that the defect noted on the transesophageal echocardiogram (B, arrow) represents an unroofed terminal coronary sinus (E). The 2-chamber view shows a dilated, unroofed coronary sinus and a dilated left atrium. Sequential cut planes of volume-rendered images of the posterior heart depict the unroofed coronary sinus in 3-dimensions (F, arrow). The arrow points to a dilated coronary sinus (G, arrow). Sequential cut planes show an intact roof proximally (H, arrow) but an unroofed terminal coronary sinus (I, arrow). The unroofed coronary sinus drains into the right atrium (J, arrow). CS: coronary sinus, IAS: interatrial septum, LA: left atrium, LV: left ventricle, RA: right atrium, RV: right ventricle, SVC: superior vena cava.
