A 10-day-old boy with distress and low blood pressure in bilateral lower and right upper limbs. a Sagittal CTA shows focal critical aortic coarctation (white arrow), small AA and aortic arch (black arrow). b Axial CTA: Aberrant right subclavian artery (RSCA) (arrow) arising from the cephalic part of DA distal to the coarctation. c Sagittal CTA: dilated MPA and LPA, large PDA (black arrow) supplying DA indicating duct dependent systemic circulation, VSD (blue arrow), small LV and enlarged RV. d Axial CTA: ASD and enlarged right side of heart. e 3DVR shows severe aortic coarctation (small arrows), large PDA (small block arrow), and aberrant RSCA (large black arrow) arises distal to the coarctation which explains the low BP measured from right UL
