Figure Legends:
Figure 1. (A, B) Fetal echocardiography showed right aortic arch and right descending aorta, left ductus arteriosus, U-shaped vascular ring and Kommerell diverticulum. (C, D) 3D HD-Flow and Glass Body Imaging of U-ring and Kommerell diverticulum (white arrow). (AO = aorta; DAO = descending aorta; LINV = left innominate vein; PA = pulmonary artery; LPA = left pulmonary artery; RPA = right pulmonary artery; SP = spine; SVC = superior vena cava; T= trachea)
Figure 2. The section of left ventricular outflow view revealed the ventricular septal defect and the aorta partially straddling the ventricular septal.
Figure 3. The frontal view of heart showed the aortic arch is located on the right side of the trachea, on which the left common carotid artery and the right common carotid artery originated.
Figure 4. (A, B) The modified cardiovascular cast showed right aortic arch with left subclavian artery, left posterior duct, CVR, Kommerell diverticulum (yellow arrow).
