Figure 3 Cardiac CT – sagittal view. Sagittal CT image illustrating the anatomy of truncus arteriosus type I. The scan reveals a dilated truncal root with calcification of the truncal valve. Both pulmonary arteries arise directly from the ascending aorta. A large VSD is visible between the right ventricle and left ventricle. A – aorta; CT – computed tomography; PA – pulmonary arteries; TV – truncal valve; VSD – ventricular septal defect; RV – right ventricle; LV – left ventricle.
