FAQ
A PFO may increase the risk of strokes because tiny blood clots elsewhere in the body can break loose and go to the heart via the blood. These tiny clots are usually filtered out of the blood by the lungs. In a person with a PFO, the clot can slip from the right atrium to the left atrium.
Rarely, a patent foramen ovale can cause a significant amount of blood to go around the lungs. This lowers blood oxygen levels, a condition called hypoxemia. Stroke. Sometimes small blood clots in veins may travel to the heart.
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.
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.
Unless there are other defects, there are no complications from a PFO in most cases. Some people may have a condition shortness of breath and low arterial blood oxygen levels when sitting or standing. This is called platypnea-orthodeoxia. This is rare.
From here, the blood higher in oxygen goes out to the lower left part of the heart and out to the rest of the body. After birth, the blood high in oxygen is already in the left atrium. So it doesn't need blood from the right atrium. That's why the foramen ovale normally closes soon after birth.
We identified 1,734 patients who underwent PFO closure after stroke or transient ischemic attack, among whom the mean age at the time of closure was 54.1 (±14.7) years. By 5 years, the cumulative rate of any complication or death was 16.3% (95% CI, 14.5–18.3%). The mortality rate was 3.4% (95% CI, 2.5–4.6%).
For those patients who need or want to avoid PFO, the panel judged anticoagulation the best alternative, although the evidence regarding stroke reduction was of low certainty. The risk of major bleeding probably increased with anticoagulation.
Are You a Candidate for PFO Closure? You may be a candidate for minimally invasive PFO closure if you: Have been diagnosed with a PFO and have had a stroke due to an unknown cause (one not attributed to a condition such as atrial fibrillation or carotid artery disease)
Patent foramen ovale occurs in about 1 in 4 people. Most people with the condition never know they have it. A patent foramen ovale is often discovered during tests for other health problems.

PFOs may not cause any symptoms. You may never know you have a PFO unless you are screened for another heart problem or experience a complication of a PFO.A patent foramen ovale is a small, flaplike opening in the wall between the upper chambers of the heart. The larger the hole, the more likely symptoms are. PFOs, on the other hand, are normal before birth but may fail to close after birth. Most people will not have any signs or symptoms directly from PFO at all. Possible PFO symptoms include: Stroke. A patent foramen ovale occurs when a hole that is always present in a newborn's heart fails to close as it should once the lungs begin to function after birth. Patent foramen ovale symptoms manifest as migraines, shortness of breath when getting up and standing, and a higher risk for certain kinds of strokes. The presence of a PFO is strongly associated with migraine with aura, migraine aura without headache, and chronic migraine.
