12 months age down girl with Fallot’s tetralogy with common AV canal defect variant presented with tachypnea and irritability A Short axis view showing RVOT infundibular narrowing and large VSD. B Axial MIP image shows RVOT narrowing, valvular pulmonary stenosis and post stenotic dilatation of MPA. C Oblique 4-Chamber view showing ostium primum ASD, common AV canal defect including common atrioventricular valve and inlet VSD. D Oblique reformatted image showing overriding aorta, peri-membranous VSD and hypertrophies RV wall. E, F reformatted images showing average right and left pulmonary arteries with no focal stenosis. G, H VR images showing overriding aorta, RVOT narrowing, valvular pulmonary stenosis with post stenotic MPA dilatation. I VR image (posterior view) shows aberrant right subclavian artery. Note normal pulmonary venous drainage into the left atrium. J VR image of right ventricular outflow (RVOT) and pulmonary arterial tree shows RVOT narrowing, valvular pulmonary stenosis and post stenotic dilatation of MPA
