What is a Percutaneous ASD Closure?

A Percutaneous ASD Closure is a common procedure used to treat ASD (or Atrial Septal Defect)  – a congenital heart defect. It’s much less invasive than open heart surgery and involves the use of a catheter to access the heart through a small incision in the groin area. A device is then deployed to seal the ASD.  The defect is closed by sewing a patch in place (if the defect is large) or by stitches (if the defect is small). 


What’s the difference between Transcatheter (Percutaneous) ASD closure and surgical ASD closure?

The main difference is the access point: Percutaneous ASD closure is done via a small incision in the groin to get into your vein (without the need to have a cut on the chest), while surgical ASD closure is done via a cut on the chest and the use of a heart lung bypass machine. Percutaneous ASD closures is less invasive than open-heart surgery and has similar outcomes and success rates.  The goal of both procedures is to improve blood flow and reduce the risk of complications such as stroke or heart failure.


Who needs a Percutaneous ASD Closure?

Anyone diagnosed with Atrial Septal Defect. To check if you’ve got ASD, you’ll need the following investigations:


What’s involved in the procedure?

The procedure is broken down into some simple steps.

  1. First, you’ll be given general anaesthetic. 
  2. The operation is guided by X-rays from the outside, and by ultrasound pictures from a probe in your throat. 
  3. A pipe is passed from a needle puncture in the leg to the heart and a wire is passed across the hole in the heart. 
  4.  A stiff tube is passed over the wire and an umbrella device is placed across the hole. The pipes are taken out and the hole in the leg (where the pipes have been) is pressed on to stop the bleeding.

The strategy used to close the ASD will depend on a number of parameters, such as size, position and any other heart defects.


What are the risks?

The complication rate is low – about 1-2%. The possible risks are:

  • Rhythm problems. These usually settle with medication, and disappear in a few weeks.
  • Bleeding. From the vein puncture point in the groin
  • Device detachment. if the umbrella moves, then it has to be recaptured. If it cannot be recaptured, then surgery may be needed to remove it;
  • Stroke.  If a small clot forms on the device or any of the pipes and moves to the brain.
  • Internal bleeding. There are wires and pipes in the heart and blood vessels used to perform the procedure, and the blood is thinned. With big devices, some patients can develop internal bleeding due to erosion.

The pros and cons of treatment will be further discussed with you in clinic.

The procedure involves closing the hole without needing to cut your chest and overall has about >95% chance of successful closure (depending on the size of the hole).
