Abstract:
Two types of coarctatio aortae in pigs are described. In the juvenile type the, funnel-shaped, narrowing in the arcus aortae was located between the origin of the a. subclavia sinistra and the aortic end of the ductus arteriosus or ligamentum arteriosum. Until now, this type has been observed only in animals with other heart anomalies. In the adult type, the narrowing of the arcus aortae was crescent-shaped and was located at the aortic end of the ductus arteriosus or ligamentum arteriosum. Histologic examination of parts of the funnel-shaped and the crescent-shaped narrowing revealed that the two types of coarctatio aortae develop differently.
