Figure 1
(A, B) Volume-rendered images demonstrate a dilated and tortuous right coronary artery (RCA) along its entire course. (C–E) Multiplanar reconstructions of computed tomography angiography depict a fistulous connection (arrowhead) between the distal RCA and the coronary sinus (CS). Also present is stenosis of the CS ostium (thick white arrow in E) with aneurysmal dilatation of the CS. (F) Volume-rendered image shows the dilated CS displacing the heart cranially. LV: left ventricle; RA: right atrium; RV: right ventricle
