A Hole in the Heart

There are two different types of “holes in the heart” a patient can be born with:

• Atrial septal defects
• Patent foramen ovale

Atrial Septal Defects

An Atrial Septal Defect (ASD) is a hole in the wall (septum) that divides the two upper chambers of the heart (the atria). This defect is present at birth and can allow blood to flow between the two chambers, which may cause the heart to work harder and lead to complications if not treated.

• Your doctor may recommend ASD closure if you have symptoms related to the defect, such as shortness of breath, frequent respiratory infections, or heart palpitations. Closure might also be advised if the ASD is causing strain on your heart or leading to other health issues.
• Large defects may require surgery, yet ASD closure is typically done using a minimally invasive procedure.
• A catheter (a thin, flexible tube) is inserted through through a needle puncture, usually in a vein in the groin, and guided to the heart. A small device, like a tiny plug, is then placed into the ASD to seal the hole.
• An overnight stay in the hospital is usually recommended for monitoring after the procedure.

Patent Foramen Ovale

A Patent Foramen Ovale (PFO), is a small, flap-like opening in the heart that didn’t close after birth. For most people, this is harmless and doesn’t cause any issues. However, in some cases, it can lead to problems, such as stroke or migraines.

• Your doctor might recommend PFO closure if you have had a stroke or transient ischemic attack (TIA) that they believe could be related to your PFO. Closure may also be suggested if you have certain types of migraines or other symptoms linked to the PFO.
• PFO closure involves a minimally invasive procedure to close the opening in the heart.
  A catheter (a thin, flexible tube) is inserted through through a needle puncture, usually in a vein in the groin, and guided to the heart. A small device, similar to a tiny umbrella, is then deployed to cover the PFO and seal the opening.
• It is usually an outpatient procedure.

If you think you may be eligible for any of these procedure, speak with your cardiologist. They can provide you with personalized information and discuss whether this procedure is a good option for your specific situation.

Exciting new procedures for other conditions such as tricuspid regurgitation are coming down the pipeline and will be available soon to our patients.
