A 25-year-old woman with coarctation of the aorta. There is increased curvature of the left ventricular contour of the left heart border. The aortic arch (Ao) is inconspicuous, and the left subclavian artery (small arrows) is dilated. Note the break in the shadow of the descending aorta (large arrow) just inferior to the aortic arch at the site of the aortic narrowing. Irregular erosions (arrowheads) on the underside of the left and right fourth ribs (rib notching) are seen.
