FAQ
Patent foramen ovale (PFO) occurs when a remnant of normal fetal anatomy abnormally persists into adulthood. It represents a benign finding in the newborn periods. If PFO persists into adulthood, it usually leads to right-to-left shunting of deoxygenated blood, which can be symptomatic or asymptomatic.
Patent foramen ovale (PFO) occurs when a remnant of normal fetal anatomy abnormally persists into adulthood. It represents a benign finding in the newborn periods. If PFO persists into adulthood, it usually leads to right-to-left shunting of deoxygenated blood, which can be symptomatic or asymptomatic.
However, a PFO can allow those clots to bypass the lungs and cross to the left side of the heart. From there, they can be pumped to the brain, causing a stroke. People who have a PFO and have had an embolic stroke of unknown cause may be at an increased risk for having a second stroke.
High-risk PFO is characterized by (D) PFO size of >3 mm (arrow) or (E) the presence of atrial septal aneurysm with (F) hypermobility of the septum during the Valsalva maneuver resulting in a large PFO size (arrow).
PFO often doesn't cause any symptoms and may not require treatment. But it can sometimes indicate stroke or mini-stroke. If you have a history of stroke or blood clots, your provider may suggest treatment.
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.
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.
Stroke is the major potential complication of PFO. People who have a PFO are slightly more likely to have a stroke than people who do not. A PFO is more likely to be the cause of stroke in a younger adult because younger people don't have as many risk factors for stroke from other causes.
The foramen ovale plays a vital role in sustaining life in-utero; however, a patent foramen ovale (PFO) after birth has been associated with pathologic sequelae in the systemic circulation including stroke/transient ischemic attack (TIA), migraine, high altitude pulmonary edema, decompression illness, platypnea- ...
