Patent Foramen Ovale (PFO) Closure

What Is Patent Foramen Ovale?

A patent foramen ovale (PFO) is a small opening between the right and left atria of the heart that normally closes shortly after birth. In some individuals, this opening remains partially open, allowing blood to pass between the chambers. While many people with a PFO have no symptoms, in certain cases it may be associated with an increased risk of stroke or other complications.

PFO closure is a procedure designed to permanently seal this opening and prevent abnormal blood flow between the atria.

How PFO Closure Is Performed

PFO closure is performed using a minimally invasive, catheter-based approach. A thin catheter is inserted into a blood vessel—typically through the groin—and guided to the heart under advanced imaging guidance. A specialized closure device is then positioned across the opening and deployed to seal the PFO.

Over time, the heart’s natural tissue grows over the device, creating a permanent closure without the need for open-heart surgery.

When PFO Closure May Be Recommended

PFO closure may be recommended for patients who have experienced an unexplained (cryptogenic) stroke or transient ischemic attack (TIA) and are found to have a PFO. It may also be considered in select patients with other conditions where abnormal blood flow through the PFO is believed to play a role.

Your cardiologist will carefully review your medical history, diagnostic tests, and individual risk factors to determine whether PFO closure is appropriate.

Benefits of Patent Foramen Ovale Closure

The primary benefit of PFO closure is reducing the risk of recurrent stroke by preventing blood clots from passing through the opening and traveling to the brain. The procedure is minimally invasive and typically involves a short recovery time.

Many patients are able to return to normal activities quickly while gaining added peace of mind from addressing a potential underlying cause of stroke.
