Clinical significance of the aortic arch and its malformations from fetus to adulthood

Nowadays, the development of intrauterine echocardiography and MR diagnostics plays a significant role in aortic arch malformations detected during the first trimester. Our aim was to detail the manifestations of vascular rings, their symptoms at different ages and their surgical treatment options in order to determine the fate of the fetus and its perinatal care. Apart from situs inversus, the presence of the right aortic arch always draws the attention to the possible presence of vascular rings, associated heart defects, genetic diseases, or chromosomal abnormalities, therefore further examinations of the fetus are necessary. In the case of a double aortic arch, severe symptoms may occur, which may require surgery after birth and in early infancy (it may be necessary to choose the place of birth!). The right aberrant subclavian artery does not form a ring and may cause mild symptoms requiring surgery at a later age with rarely associated truncus carotid.
