Figure 1. Coronal multiplanar reconstruction from CT angiography with a 1.25 mm slice thickness and cardiac gating technique demonstrates findings compatible with tetralogy of Fallot [right ventricular hypertrophy, right ventricular outflow tract obstruction (#), ventricular septal defect (*)]. The aorta (AO) is to the left of the pulmonary artery (PA). LV, left ventricle; RV, right ventricle.

Figure 2. Oblique coronal multiplanar reconstruction from CT angiography with a 1.25 mm slice thickness and cardiac gating technique demonstrates the fibrous continuity between the mitral and aortic annuli (bold arrows), a large subaortic ventricular septal defect (*) and overriding of the aorta (AO). AV, aortic valve leaflets; MV, mitral valve leaflets as shown by dash arrow; LV, left ventricle; and RV, right ventricle.

Figure 3. Volume-rendered 3D reconstruction of the heart and great vessels from multidetector CT demonstrates the aorta (AO) located anterior and leftward to the pulmonary artery (PA). Single coronary artery comes off the right coronary cusp. RCA, right coronary artery; LCA, left coronary artery; LCX, left circumflex artery; LAD, left anterior descending artery; RA, right atrium; RV, right ventricle; and LV, left ventricle.
