Figure 6. A 12-month-old girl with short-segment aortic coarctation. (a) Sagittal and (b) coronal multiplanar reformations clearly demonstrate the location and extent of the narrowing (arrow) just beyond the left subclavian artery (S), which is mildly dilated. Posterior collateral intercostal arteries (arrowheads) arising distal to the coarctation and post-stenotic dilatation of the proximal descending aorta are also seen. A, aortic arch; DA, descending aorta.
