Can I exercise with a PFO?
PFO's typically do not disrupt heart function and people are able to exercise and carry out all activities normally. However, some people with PFOs can be at an elevated risk of stroke or suffer other symptoms due to a significant drop in oxygen levels.
How do you fix a patent foramen ovale?
A Patent Foramen Ovale (PFO) Repair, or closure, is a procedure that's done to close the flap in the wall of the atrial septum, also called a patent foramen ovale.

What is considered a small PFO?
A patent foramen ovale (PFO) is a hole in the heart that didn't close the way it should after birth. During fetal development, a small flap-like opening — the foramen ovale (foh-RAY-mun oh-VAY-lee) — is normally present in the wall between the right and left upper chambers of the heart (atria).
What is Fossa Ovalis?
The fossa ovalis is a depression in the right atrium of the heart, at the level of the interatrial septum, the wall between right and left atrium. The fossa ovalis is the remnant of a thin fibrous sheet that covered the foramen ovale during fetal development.
Is PFO closure dangerous?
Complications from a PFO closure and side effects may include atrial fibrillation, an ischemic stroke as a result of the procedure, bleeding from the site where the device is guided into the body, blood clots in the leg or lung, injury to the heart, or embolization of the device (note that while these complications may
Does PFO closure prevent stroke?
The CLOSE trial revealed that PFO closure significantly reduced the risk of recurrent stroke compared with antiplatelet therapy (HR, 0.03; 95% CI, 0–0.26; P<0.001; Table 1).
What are the three fetal shunts?
Three major shunts found in the fetus are the foramen ovale and ductus arteriosus, which divert blood from the pulmonary to the systemic circuit, and the ductus venosus, which carries freshly oxygenated blood high in nutrients to the fetal heart.
