Although the vast majority of people with patent foramen ovale are asymptomatic, a patent foramen ovale is believed to act as a pathway for chemicals or thrombus that can result in a variety of clinical manifestations, including stroke, migraine headache, decompression sickness, high-altitude pulmonary edema, and ...
In general, patent foramen ovale doesn't cause symptoms or health complications, but it can increase your risk for developing the following: Migraine headaches. Blood clots. Low oxygen levels (Platypnea orthodeoxia) Shortness of breath and dizziness if you suffer from low oxygen levels.
A foramen ovale directs the oxygen-rich blood from the umbilical cord in a fetus's right upper chamber (right atrium) to the left upper chamber (left atrium). From there, the blood goes to the left side of the fetus's heart and provides oxygen to fetus' brain. The foramen ovale normally closes after birth.
There are usually no symptoms for patent foramen ovale (PFO). If present, symptoms for PFO may include: Severe migraine headache. Transient ischemic attacks (TIA)

Abstract. Patent foramen ovale (PFO) is implicated in platypnea-orthodeoxia, stroke and decompression sickness (DCS) in divers and astronauts. However, PFO size in relation to clinical illness is largely unknown since few studies evaluate PFO, either functionally or anatomically.
If a PFO exists, a little blood can flow between the atria through the flaps. This flow is not normal. The condition is most important because it raises the risk for stroke. Blood clots can travel from the right atrium to the left atrium and out to blood vessels of the body.
Conclusions: The finding of an ECG crochetage pattern may help to identify stroke patients with PFO, may help to streamline their diagnostic workup, and may warrant future studies to determine its value in stratifying stroke risk in patients with PFO.
Rarely, a patent foramen ovale can cause a significant amount of blood to go around the lungs. This lowers blood oxygen levels, a condition called hypoxemia. Stroke. Sometimes small blood clots in veins may travel to the heart.
