Abstract

Coarctation of the aorta is an unusual congenital anomaly which is noted about once in 1,550 autopsies.1 Bonnet2 divided the disorder, on the basis of the anatomic lesions, into the so-called infantile and adult types. In the infantile type the coarctation characteristically occurs between the origin of the left subclavian artery and the mouth of the ductus arteriosus. The anomaly may be noted as diffuse narrowing of the isthmus of the aorta, the presence of a mere fibrous cord or the complete absence of the isthmus. The adult type of coarctation is characterized by stenosis of the aorta occurring at or just distal to the insertion of the ductus arteriosus. The ductus is usually obliterated; Abbott3 found that it was noted as being patent in only 17 of the autopsy reports for the 200 cases she reviewed. In the infantile type the ductus is usually patent, its
