A patent foramen ovale (PFO) is a hole in the wall that that separates the heart's two upper chambers (atria). All babies have this opening (called a foramen ovale) before birth to allow blood to bypass the lungs. Shortly after birth, the tissue usually grows together and closes the hole.
Definition. Patent foramen ovale (PFO) is a hole between the left and right atria (upper chambers) of the heart. This hole exists in everyone before birth, but most often closes shortly after being born. PFO is what the hole is called when it fails to close naturally after a baby is born.
PFO is common, presenting in about one in four people. But more than 95% of those with the condition will never find out, as most don't suffer PFO symptoms or health issues. Heart specialists don't often need to diagnose or treat PFO in healthy patients.
How is patent foramen ovale treated? Antiplatelet medicines such as aspirin, to help prevent blood clots. Anticoagulant medicines such as warfarin, to help prevent blood clots. Closure of the PFO with a catheter-based procedure. Closure of the PFO during heart surgery.
But, in most infants, this small hole naturally closes very soon after birth. But in some cases, it does not. It's a normal finding in children but not in adults.
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.
PFO TREATMENT OPTIONS BLOOD-THINNING. MEDICATION. OPEN HEART SURGERY TO CLOSE THE PFO. Today, open heart surgery is rarely performed to close a PFO unless it is performed together with another surgery or the heart team determines that device closure with an occluder is not technically possible. PFO CLOSURE.
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.
MEDICATION. Your doctor may prescribe blood-thinning medication to reduce your chance of having blood clots. Aspirin (taken daily) is the recommended medication for most patients to reduce the risk of having another ischemic stroke. Some physicians recommend stronger blood-thinning medications called anticoagulants.
Exams and Tests If a PFO exists, tiny air bubbles will be seen moving from the right to left side of the heart.
