Figure 4:

Preoperative appearance of tetralogy of Fallot with absent pulmonary valves in a male infant. (A) Sagittal oblique maximum intensity projection (MIP) CT image shows right ventricular hypertrophy (white arrow), VSD (black double arrow), and overriding of the aorta. (B) Axial oblique MIP CT image shows hypoplasia of pulmonary valve ring with absent pulmonary valves (black arrow). The MPA and its branches (right > left) are dilated. (C) Volume-rendered image further confirms the pulmonary stenosis (black arrow) and massive dilatation of the MPA and RPA. Ao = aorta, LPA = left pulmonary artery, LV = left ventricle, MPA = main pulmonary artery, RPA = right pulmonary artery, RV = right ventricle, VSD = ventricular septal defect.
