Figure 8 Computed tomography images. A-C: Axial (A and B) and coronal reformatted images (C) of computed tomography angiography in a child with tetralogy of Fallot showing systemic aortopulmonary collateral artery in the right paratracheal location arising from the right subclavian artery and reforming the right pulmonary artery; D and E: Axial image of computed tomography angiography showing a large atrial septal defect in a patient with tetralogy of Fallot consistent with pentalogy (D); Sagittal reformat of another patient showing a small muscular ventricular septal defect (block arrow) in addition to the perimembranous ventricular septal defect (E).
