Atrial Septal Defect (ASD) Closure

What is an atrial septal defect?

The heart is divided into four chambers and the upper chambers are divided by a wall called septum. Atrial septal defect is a congenital defect seen in the heart, when a hole is present in the septum

How is atrial defect corrected?

Atrial defect can be corrected by either of the following methods


  • An incision is made through the breast bone to reach the heart
  • The defect is then closed  with either stitiches or a patch, depending upon the size of the hole
  • The chest incisions are then closed


Non surgical closure

  • A small, thin, flexible tube (catheter) is inserted into a blood vessel in the groin and guided into the heart.
  • Once the catheter is in the heart, the surgeon passes a special device, called a septal occluder, into the ASD.
  • The catheter tip is moved into place, and the device is pushed out of the catheter, across the atrial septal defect. The umbrella patch is then opened to cover the hole and secured in place.
