FAQ
Procedures to close a patent foramen ovale include: Device closure. In this procedure, the provider inserts a thin, flexible tube called a catheter into a blood vessel in the groin area. The catheter tip has a device to plug the PFO .
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 opening is supposed to close soon after birth, but sometimes it does not. In about 1 out of 4 people, the opening never closes. If it does not close, it is called a PFO. The cause of a PFO is unknown.
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.
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.
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.
Patent foramen ovale causes 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.
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.
The foramen ovale usually closes 6 months to a year after the baby's birth.
Possible Complications 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. Rarely, people with PFOs may have a higher rate of a certain type of stroke (called paradoxical thromboembolic stroke).
