Everyone has a PFO at birth. It is a normal part of the circulation of a fetus. But, in most infants, this small hole naturally closes very soon after birth. But in some cases, it does not.
For small PFOs without associated interatrial septal aneurysm, the 25-mm size Cribriform, PFO occluder, or Helex is preferred. Using devices smaller than 25 mm in adults is not required and may increase the risk for device embolization.
This condition is not treated unless there are other heart problems, symptoms, or if the person had a stroke caused by a blood clot to the brain. Treatment most often requires a procedure called cardiac catheterization, which is performed by a trained cardiologist to permanently seal the PFO.
Most PFOs don't need to be closed. Most PFOs cause no symptoms or complications. Larger PFOs may cause stroke. People with symptomatic or large PFOs may benefit from a procedure to close the hole.
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.
The foramen ovale usually closes 6 months to a year after the baby's birth.

Usually, patent foramen ovale causes no problems. But PFO may let a blood clot travel from the right to the left side of your heart. Your heart could pump the clot into your body. If the clot reaches your brain, it could cut off the blood supply.
