Fig. 1

Coronary computed tomography angiography (CCTA) images (A, B) and phase-contrast cardiac magnetic resonance (CMR) images (C, D). A Normal ostium of the right coronary artery (RCA) with short proximal normal segment (6 mm length, arrow). B Giant aneurysm of the RCA with dilatation up to 5.0 cm (arrow) and coronary artery fistula with a tortuous course, ultimately draining into the distal superior vena cava (SVC) (arrowhead). C Systemic blood flow (Qs) measured at the level of the proximal ascending aorta was 118 ml. D Pulmonary blood flow (Qp) measured at the level of the pulmonary trunk was 160 ml. Qp/Qs ratio was 1.36, indicating a significant left-to-right shunt
