Atrial Septic Defect Repair

An atrial septal defect is a hole in the wall (septum) between the left and right atria. If there is a large hole, oxygen-rich blood from the left atrium flows back into the right atrium and gets pumped back to the lungs again. This causes more work for the heart.

If the defect does not close on its own, heart surgery is required to close the hole. This is achieved through sutures, or in some cases, through the use of a closure device such as a Dacron patch.
