Aortic coarctation is a congenital narrowing of the aortic lumen, usually situated between the origin of the left subclavian artery proximally and the junction of the aorta and the ductus arteriosus distally. When the coarctation is an isolated finding, the wall of the aorta is pinched in a waist-like fashion, the ascending and descending portions of the arch tending to expand above and below the site of coarctation. The narrowing may consist of an elongated and diffuse tract, proximally to the ductus arteriosus (Fig. 3.13.1), or of a sharp constriction in the area of aortic insertion of the arterial duct, with a diaphragmatic shelf of fibrous tissue protruding into the lumen, often with a pin-hole orifice representing the only communication between the ascending and descending aortic segments (Fig. 3.13.2). Aortic arch hypoplasia of mild or severe degree may also be present (Figs. 3.13.3-3.13.5).
