A healthcare provider may recommend a PFO closure procedure if: You've had a transient ischemic attack (TIA) more than once. You've had cryptogenic (from an unknown cause) strokes more than once. You have a low level of oxygen in your blood.
PFO closure may be offered to younger patients (e.g., <30 years) with a single, small, deep stroke (<1.5 cm), a large shunt, and absence of any vascular risk factors that would lead to intrinsic small-vessel disease such as hypertension, diabetes, or hyperlipidemia (level C).
Definition. Patent foramen ovale (PFO) is a hole between the left and right atria (upper chambers) of the heart. This hole exists in everyone before birth, but most often closes shortly after being born. PFO is what the hole is called when it fails to close naturally after a baby is born.
If you were born with a hole in your heart that never closed, known as a patent foramen ovale (PFO), you may need a procedure to correct it. Penn Medicine cardiologists use interventional techniques to close a patent foramen ovale without opening your chest for surgery.
Having a PFO as an adult or older child is not normal. But it occurs in many people. It may be slightly more common in younger adults compared with older adults.
We don't know exactly why a PFO develops. It may be genetic, meaning it runs in families. The condition also seems to be found more frequently in people who regularly have migraines with auras.

Most PFOs require no treatment. People who have no risk factors for stroke or any history of traveling blood clots usually do not get treatment. Your healthcare provider may want to treat your PFO if you have had problems from these traveling blood clots, like stroke.
This new flow helps push the patent foramen ovale closed. The blood can no longer flow directly between the upper two heart chambers. Instead, it flows from the right side of the heart into the baby's lungs to pick up oxygen, and then the left side of the heart sends the oxygen-rich blood out to the body.
In general, patent foramen ovale doesn't cause symptoms or health complications, but it can increase your risk for developing the following: Migraine headaches. Blood clots. Low oxygen levels (Platypnea orthodeoxia)
