Congenital aortic constriction

Aortic constriction accounts for about 5 to 8% of all types of congenital heart disease. In 1760, Morgagni discovered the disease during autopsy. Its main lesion is aortic localized short lumen stenosis or occlusion resulting in aortic blood flow disorders. The majority of the aortic constriction lesions (over 95%) are at the junction of the distal aortic arch with the descending thoracic aorta, that is, the aortic isthmus, adjacent to the arterial duct or the ligamentous area. However, in rare cases, the constricted segment can be located in the aortic arch, descending thoracic aorta or even abdominal aorta. Sometimes the aorta may narrow in two places. Very few patients have a family history. The disease is more common in men, with a male to female ratio of 3 to 5: 1.
