    Interruption of the Aortic Arch

  • In a child with coarctation of the aorta, the aorta is too narrow at the portion just after the upper-body arteries branch off - this obstructs blood flow.

  • The more the aorta is narrowed, the more severe the symptoms will be.

    Coarctation of the Aorta

  • Here, a team diagnosed Sarah with moderate to severe aortic stenosis, which means that the heart valve that opens to allow blood to flow into the aorta is malformed and doesn't function correctly.

  • The aorta is the main artery that carries oxygenated blood out of the heart to the body.

    Coarctation of the Aorta

    Tricuspid Atresia

  • The aorta is attached to the right-sided pumping chamber (ventricle), instead of the left.

    Transposition of the Great Arteries
