Most children feel better right after surgery, although some may continue to have breathing symptoms for some time after surgical repair. This is most often due to weakness of the trachea because of the pressure on it before surgical repair. In rare cases, if the arch is pressing down very hard on the airway, the child can have severe breathing difficulty that leads to death.

A double aortic arch may occur in other congenital heart defects, including: Tetralogy of Fallot Truncus arteriosus Transposition of the great arteries Ventricular septal defect Double aortic arch is very rare.
The aortic arch functions as a manifold to fill the three arteries that branch off of it and to continue the remainder of the blood flow lower on the body.
The muscle tone of the aorta plays a big part in the ability of the heart to fully expand and in the overall control of blood pressure in the body. It also helps create back pressure on blood ejected from the ventricles during systole, which pushes blood into the coronary arteries to provide circulation to the heart muscle.
The shape of the aortic arch creates some resistance to blood flow. In some people, the angle of the aortic arch coupled with certain medical conditions can lead to aortic dissection where the ascending aorta meets the aortic arch. Aortic dissection occurs when a tear in the tunica intima allows blood to be pushed between the tunica intima and the tunica media. The build-up of blood causes a separation of the two layers and a bulge is created on the side of the aorta.
Males over the age of 60 have the highest risk as a group for aortic dissection. People with lifestyles that include episodes of intense strain or stress—such as power weightlifting or the use of cocaine—also have an increased risk of aortic dissection. Marfan syndrome and Turner's syndrome are two uncommon genetic conditions that can lead to an increased risk of aortic dissection.
Turner's syndrome may cause coarctation of the aorta or malformation of the aortic valve. Marfan syndrome can cause aortic aneurysm due to the weakening of connective tissues, including those that make up the arteries.
