Atrial Septal Defect Repair

Also known as: ASD repair, ASD surgery, ASD closure.

What is atrial septal defect repair?

An atrial septal defect (ASD) is a hole in the wall between the two upper chambers of the heart. It allows blood to flow from the left side of the heart to the right side improperly. An ASD repair is a surgery that involvessewing a patch onto the hole to close it if closed by surgery or placing a device to close the hole if done by catheter intervention.

What happens during the procedure?

The child is placed under general anesthesia. If the patient has the hole closed by catheterization then a catheter, or tube, is inserted into a blood vessel to the hole. A balloon is inserted through the catheter to measure the hole. Then the closure device is inserted into the hole to repair the defect.  Some ASDs cannot be closed by catheter device placement and require open heart surgery. For ASDs closed by surgery the patient will also be placed under anesthesia and on a heart lung bypass machine. A patch will then be sewn on the hole to close it.

Is any special preparation needed?

The child may need to stop taking some medications and refrain from food or drink for a certain amount of time before the procedure.

What are the risk factors?

The risks of atrial septal defect repair include broken blood vessels, bleeding, infection, fluid around the heart or the risk of the closure device moving or falling out of place.
