Figure 7 (A, B): Congenital anomalies. Four-chamber CT image (A) shows a defect in the region of the fossa ovalis (arrow), with the contrast jet extending from the left atrium to the right atrium. Axial CT image (B) shows a sinus venosus atrial septal defect (arrow) between the superior vena cava (SVC) and the left atrium (LA). An anomalous pulmonary vein (RSPV) is also seen draining the right upper lobe into the superior vena cava
