Can PFO cause ocular migraine?
Migraine, especially with aura, has also been linked with PFO. A randomised controlled study (Migraine Intervention with STARFlex Technology) detected PFO in 60.2% of patients with migraine (40% with large shunts), much higher than that expected in the normal population.
Does PFO closure help migraines?
Patent foramen ovale (PFO) closure in addition to medical therapy may be associated with significant reductions in the number of migraine days and attacks when compared with medical treatment, according to a study published Feb. 8 in the Journal of the American College of Cardiology.

Can a PFO cause fatigue?

Should I have my PFO closed?
If you have, then closing the hole can reduce the risk of recurrent strokes. If the PFO is sizable, it may allow large amounts of blood to move back and forth between the left and right sides of your heart. This can create pressure and cause your heart to enlarge. Closing the PFO can protect your heart’s function.
