What is ​Interruption of the Aortic Arch (IAA)?

Also known as: interrupted aortic arch, IAA

As the aorta carries blood from the heart to the rest of the body, it arches upward before bending around and down. When blood flow is cut off at any point along this arch, it is known as interruption of the aortic arch or an interrupted aortic arch (IAA).
