INTERRUPTED AORTIC ARCH IN TWO SIBLINGS

Abstract
Girls [2] with identical malformations consisting of complete interruption of the aortic arch, type B, ventricular septal defect, patent ductus arteriosus and anomalous origin of the right subclavian artery are described. Five other unrelated patients with interrupted aortic arch were investigated. Of their 6 siblings, 1 had a coarctation of the aorta, while 5 were normal. This may contribute to elucidation of the genetics of this entity and may improve genetic counselling.
