A narrowing of the AORTA in the vicinity of the insertion of the ductus arteriosus. It is a congenital abnormality but may not be discovered until well into childhood or adolescence. The diagnosis is easily made by discovering a major difference between the blood pressure in the arms and that of the legs. If untreated it leads to hypertension and heart failure, but satisfactory results are now obtained from surgical treatment, preferably in infancy. Paediatricians screen for coarctation by feeling for femoral pulses, which are absent or weak in this condition.
