Atrial Septal Defect ASD

  • Atrial Septal Defect Secundum

    A defect is present in the central part of the "Atrial Septum" (the partition separating the Atriums). This allows red blood to pass through into the right side of the heart, leading to enlargement of the Right Ventricle and excessive flow in the lung circulation.

    Defects of this type are common. They seldom lead to symptoms during childhood and may not be detected until school age or later. Symptoms are likely to develop by early to middle adult life.



    After Device Closure

    Defects of this kind may be repaired surgically during childhood (before they are likely to lead to damage to the heart or lungs.  Alternatively they can be closed, in suitable cases, with a catheter procedure (Device Closure).

    The Device is introduced through a Heart Catheter, which has been passed up from a vein in the leg. The Device is made of collapsible metal mesh, with thin membranes inside. Once inside the ASD it will become covered by natural tissue within a few weeks.
