Atrial Septal Defect Repair

Also known as: ASD repair

Catheterization procedure

Before the procedure, the surgeon will place your child under general anesthesia. They will then insert a balloon-like tool through a catheter, or tube. Once they have inserted the catheter into a blood vessel, the balloon can measure the hole and the surgeon can place the closure device in the heart. 

Atrial septal defect surgery procedure

ASD heart surgery may be necessary for patients whose conditions cannot be treated by catheter device placement. If your child needs surgery, the surgeon will place them under anesthesia and connect them to a heart lung bypass machine. They will then sew a patch over the hole to close it. 

Preparation and risk factors

Your child may need to stop taking some medications and/or refrain from eating and drinking before the procedure. The risks of atrial septal defect treatment include broken blood vessels, bleeding, infection, and fluid around the heart. It is also possible for the closure device to move or fall out of place.
