18 months age girl with TOF DORV variant with clinical history of cyanosis and irritability. A MPR sagittal image showing infundibular RVOT stenosis with average MPA and RPA. B Axial MIP image showing concentric RVOT luminal narrowing. C Oblique reformatted image showing Overriding aorta with ventricular septal defect (VSD) with more alignment of aorta to the right ventricle. D, E Axial MIP and MPR sagittal images showing PDA connected to LPA. F, G Axial and coronal MIP images showing superior sinus venosus ASD. Note Right superior and inferior pulmonary veins abnormal drainage by common ostium into the right sided atrium representing partial anomalous pulmonary venous connection. H–J Coronal MinIP image, Axial MIP and coronal MIP images showing left isomerism evident by bilateral left bronchial morphology (hypoarterial bronchus) (G), left sided polysplenia (H) as well as azygous continuation of IVC (J). K VR image anterior view showing MPA, RV, RA, ascending aorta and aortic arch with its branches. Note left atrial appendage morphology of the right atrial appendage. L VR image of the aorta and pulmonary arterial tree showing average sized MPA, RPA and LPA with PDA seen Connecting to LPA. M, N VR images posterior view showing abnormal drainage of right superior and inferior pulmonary veins by common ostium into the right sided atrium (partial anomalous pulmonary venous return) as well as azygous continuation of IVC. Note PDA arising from the inferior aspect of aortic arch
