D, E VR color rendering and CR showed complete absence of the parietal wall of the CS. PLSVC was connected to RSVC via Inn.V. F CR cross-sectional view visualized the spatial relationship between the ASD and the CS defect. RA right atrium, and the section of PLSVC(*) flowing into the left atrium also displayed. CS coronary sinus, LA left atrium, RSVC right superior vena cava, PLSVC persistent left superior vena cava, ASD atrial septal defect, Inn.V. innominate vein
