Coarctation of the Aorta HD

  • A narrow area (stricture) is present in the aorta and leads to restricted blood flow to the lower part of the circulation. Blood pressure in the arms and head is high, whilst that in the legs is low. Heart failure may develop. In most cases surgical repair is needed, sometimes in the early weeks of life.

    Repair may involve surgical removal of a short segment of aorta, including the stricture (with the ends sewn back together) or use of the artery to the left arm to create a flap, which is turned down to enlarge the narrow section.

    Alternatively it may, in some cases, be possible to deal with the problem with a balloon catheter.

    Coarctation Repair

    Conventional repair involves the removal of the narrow segment with the ends being sewn together ("end to end").

     

    Subclavian Flap

    With this type of repair the left arm artery (Subclavian Artery) is used to produce a flap to enlarge the Aorta and repair the Coarctation.

     

    Balloon Angioplasty

    A catheter with an inflatable balloon is introduced from an artery in the leg. The balloon is inflated to enlarge the narrow area.
