Patent Foramen Ovale (PFO)

What is PFO?

A foramen ovale is hole in the heart that is a normal part of fetal development. The hole usually closes and seals within a few months of birth. For about 25-33 percent of people, the hole doesn’t close completely, allowing a small amount of blood to pass from the right to left side of the heart. This is called a PFO. Most of the time PFOs do not cause any symptoms and do not require any treatment if found by accident.

When would you need a PFO closure?

While PFOs are common, in rare cases, they allow a blood clot to pass from the right to the left side of the heart. The clot can travel to the brain causing a stroke. Most strokes are caused by other conditions such as atrial fibrillation, abnormalities in blood vessels, clots on artificial valves or clotting disorders. A stroke that cannot be attributed to these or other causes is called a cryptogenic stroke. If the PFO is believed to have been a factor in cryptogenic stroke, a cardiologist might perform a PFO closure to prevent future strokes. Other treatment options include blood thinning medications or, in rare cases, surgery.
