[Atresia of the aortic isthmus from the radiological point of view].

The most important angiographic features of atresia of the aortic isthmus are illustrated by three patients. The first patient to have reached an advanced age despite atresia of the aortic isthmus is reported and the diagnosis was confirmed at autopsy. The haemodynamic effects, the age at operation and the incidence of other associated cardiovascular malformations are discussed with reference to the literature.
