A patent foramen ovale (PFO) is a hole in the heart that didn't close the way it should after birth. The hole is a small flaplike opening between the upper heart chambers. The upper chambers of the heart are called the atria.
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.
PFO was found in 25 to 30 percent of individuals in an autopsy study and in a community-based transesophageal echocardiography (TEE) study 4,5.
PFO itself usually does not cause any symptoms. PFO can occasionally result in complications. The most serious of these is stroke. Most people will not need treatment for a PFO.
Most PFOs don't need to be closed. Most PFOs cause no symptoms or complications. Larger PFOs may cause stroke. People with symptomatic or large PFOs may benefit from a procedure to close the hole.
Unless there are other defects, there are no complications from a PFO in most cases. 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.
It is estimated that 25% - 30% of ischemic strokes are of unknown cause. One possible factor that may have contributed to a stroke of unknown cause is the presence of a patent foramen ovale.
Patent applications: the three criteria Novelty. This means that your invention must not have been made public – not even by yourself – before the date of the application. Inventive step. This means that your product or process must be an inventive solution. Industrial applicability.
