• #1 Patent Foramen Ovale (PFO): Symptoms, Causes & Treatment

  https://my.clevelandclinic.org/health/diseases/17326-patent-foramen-ovale-pfo

  Most of the time, people with PFO dont have symptoms and wont need treatment. […] Possible PFO symptoms include: Stroke. […] Transient ischemic attack (TIA) or mini-stroke that impairs your ability to move your arms or legs, and affects vital organs such as the brain, small intestine, large intestine (colon) or kidneys. […] Many children with PFO find the flap seals completely on its own during their first three years. Many people who still have PFO as adults lead long, full lives. […] Patent foramen ovale (PFO) is a small communication between the upper right and left chambers of your heart. PFO affects about 25% of people. PFO often doesnt cause any symptoms and may not require treatment. But it can sometimes indicate stroke or mini-stroke.

  Patent foramen ovale occurs in about 1 in 4 people. Most people with the condition never know they have it. A patent foramen ovale is often discovered during tests for other health problems. […] A patent foramen ovale is a small, flaplike opening in the wall between the upper chambers of the heart. It usually causes no symptoms and rarely requires treatment. […] Possible complications of patent foramen ovale may include: Low blood oxygen. 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. […] Some studies have found that patent foramen ovales (PFOs) are more common in people with unexplained strokes and migraines with aura. But more research is needed. Usually, there are other reasons for these conditions. It’s often just a coincidence a person also has a PFO.

  When the flap doesnt fully close, its called a patent foramen ovale (PFO). This occurs in about one in four people, with the vast majority having no symptoms or medical problems. […] 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 dont suffer PFO symptoms or health issues. Heart specialists dont often need to diagnose or treat PFO in healthy patients. However, some people experience symptoms and complications of PFO, such as migraine headaches in adults and an increased risk of blood clots or stroke. […] In general, patent foramen ovale doesnt 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, Increased chance of decompression illness (the bends) in scuba or deep-sea divers, Stroke, Transient ischemic attack (TIA), which may be an early warning sign of a stroke. Sometimes called a ministroke, Heart attack (rare), Vision loss. […] In some cases, an exam following a stroke or transient ischemic attack may be the first time a PFO is discovered in the heart.

  A hole in your heart would seem to be the very definition of a „problem.” Yet more than a quarter of the population has one type of hole in the heart, called a patent foramen ovale (PFO), and for most people it causes no adverse health effects. In fact, the vast majority of those affected don’t even know it. […] Problems can arise when pressures within the heart change for various reasons and the foramen ovale flap never completely sealed, allowing blood to flow from the right atrium to the left. If that blood contains a clot it can travel elsewhere in the body including the brain, which could lead to a stroke.

• #5 Patent Foramen Ovale (PFO) – Divers Alert Network

  https://dan.org/health-medicine/health-resources/diseases-conditions/patent-foramen-ovale-pfo/

  Patent foramen ovale (PFO) is a common congenital heart defect. […] With a patent foramen ovale, if the pressure in the right atrium rises above the pressure in the left atrium, blood can flow from the right to the left atrium (known as a right-to-left shunt or RLS). […] The risk of DCI is 2.5 times greater in divers with a PFO (and the risk of neurological DCI is 4 times greater). […] The overall risk of neurological DCI is still low, even in a person with a PFO. […] A spontaneous shunt without provocation or a significant provoked right-to-left shunt with VGE following diving is a risk factor for DCI with cerebral, spinal, vestibulocochlear or cutaneous manifestations. […] Half of the divers in the studies with RLS-related DCI have a PFO that is a centimeter in diameter or larger.

  Usually a patent foramen ovale is diagnosed when tests are done for another health concern. If your health care provider thinks you may have a patent foramen ovale (PFO), imaging tests of the heart may be done. […] If you have a patent foramen ovale, this type of echocardiogram usually shows blood moving between the upper heart chambers. […] If you have a PFO and low blood oxygen levels or an unexplained stroke, you may need a procedure to close the hole. […] Most people with a patent foramen ovale don’t need treatment. If a PFO is found when an echocardiogram is done for other reasons, a procedure to close the hole usually isn’t done. […] Your doctor may recommend medicines to try to reduce the risk of blood clots crossing a patent foramen ovale. Blood thinners may be helpful for some people with a patent foramen ovale who’ve had a stroke. […] If you know you have a patent foramen ovale, but don’t have symptoms, you probably won’t have any restrictions on your activities.

  Most of the time, a PFO itself causes no symptoms. Sometimes symptoms do result from the complications of a PFO, such as stroke. […] Stroke is the major possible complication of a PFO. People who have a PFO are slightly more likely to have a stroke than people who don’t. A PFO is more likely to be involved in a stroke of a younger adult. That’s because younger people don’t have as many risk factors for stroke from other causes. Stroke can cause these symptoms: […] Most strokes don’t result from a PFO. Even people who have a PFO often have strokes for other reasons. […] A PFO can cause other complications as well. These include:

  Patent foramen ovale (PFO), a hole in the heart that can be present at birth, is a common structural heart defect. It occurs in about 25 percent of all newborns, but most people do not experience problems because of it. […] Often a PFO is not diagnosed until a child or adult with this defect has a transient ischemic attack (TIA) or a stroke. TIAs produce stroke-like symptoms that last less than 24 hours. Symptoms of PFO include any of the following TIA or stroke symptoms: Sudden numbness or weakness in the face, arm or leg (especially on one side of the body), Difficulty speaking or understanding words or simple sentences, Sudden blurred vision or decreased vision in one or both eyes, Difficulty swallowing, Dizziness, loss of balance or coordination, Brief loss of consciousness, Sudden paralysis in one part of the body, Severe migraines.

  Most people with a patent foramen ovale don’t have symptoms. Some discover they have a PFO after having a heart imaging test for other reasons. […] Signs that you may have a PFO include: […] A stroke or „ministroke” with no apparent cause. If a blood clot goes through the PFO and blocks a blood vessel leading to the brain, this can cause a stroke or a milder „ministroke” known as a transient ischemic attack (TIA). Having a stroke or TIA of unknown cause especially before the age of 55 is the most common way people learn they have a PFO. […] Hypoxemia, or low oxygen levels in the bloodstream. This can happen when too much blood flows through the PFO and is pumped out to the body, instead of circulating through the lungs (where it would receive oxygen). Hypoxemia can make you feel dizzy or short of breath.

  https://www.mountsinai.org/health-library/diseases-conditions/patent-foramen-ovale

  Infants with a PFO and no other heart defects do not have symptoms. Some adults with PFOs also suffer from migraine headaches. […] This condition is not treated unless there are other heart problems, symptoms, or if the person had a stroke caused by a blood clot to the brain. […] Rarely, people with PFOs may have a higher rate of a certain type of stroke (called paradoxical thromboembolic stroke). In a paradoxical stroke, a blood clot that develops in a vein (often leg veins) breaks free and travels to the right side of the heart. Normally, this clot would then continue to the lungs, but in someone with a PFO, the clot could pass through the hole to the left side of the heart. It may then be pumped out to the body, travel to the brain and become stuck there, preventing blood flow to that part of the brain (stroke). […] Having a very mobile septum along with a PFO may lead to a higher risk for having a stroke.

• #18 Diving into the Comorbidity Between Migraine and Patent Foramen Ovale

  https://www.migrainedisorders.org/diving-into-the-connection-between-migraine-and-patent-foramen-ovale/

  The foramen ovale is a “hole” between the top two chambers of the heart (atria) in fetuses that is necessary for blood to bypass the lungs while the lungs are not functioning. Normally, the hole closes shortly after birth, but in some individuals it stays open and is known as patent (open) foramen ovale (PFO). This occurs in approximately 25% of the general population. This hole between the atria may result in abnormal blood flow from the right side of the heart to the left. […] Interestingly, the presence of a PFO is strongly associated with migraine with aura, migraine aura without headache, and chronic migraine. […] Lastly, chronic migraine (with or without aura) is more prevalent among those with PFO (66%) compared to the general population and those with episodic migraine. […] Most of the time, many people are unaware they have patent foramen ovale. It is usually discovered during testing for another condition, as it is very common and it usually does not cause symptoms.

  Patent Foramen Ovale is a type of hole in the heart that occurs after birth when the foramen ovale does not close. […] PFO are often undiagnosed as there are no obvious signs and symptoms or complications with an undiagnosed PFO. In adulthood, many PFOs are found after presenting with a stroke or cerebral vascular event (CVA). These strokes with no known causes are called Cryptogenic strokes (CS). It is thought that a PFO may potentially increase the risk of a Cryptogenic stroke in some patients. […] PFOs have also been linked to migraine headaches with aura although the mechanism of cause/ effect is not well understood. There are currently several studies looking at a causal between migraines and PFOs.

  Patent Foramen Ovale (PFO) is a hole in the heart that can be congenital or acquired. […] If you’ve been diagnosed with a patent foramen ovale, you’re likely wondering if it poses a threat to your cardiac health. Fortunately, this condition is usually asymptomatic and does not require treatment. However, it can be a risk factor for stroke and heart attack in some people. […] If you’re lucky, a PFO will cause no noticeable symptoms. However, if it results in a drop in your blood oxygen levels, you may experience a variety of symptoms, including: headaches, dizziness, chest pain (angina), shortness of breath, fatigue or weakness that does not go away with rest, feeling faint. […] Now you know what a patent foramen ovale is and why it’s so important to get checked out if you have symptoms. If you are diagnosed with a PFO, your doctor may recommend treatment based on your symptoms and medical history. That said, PFO does not always require treatment.

  Patent foramen ovale (PFO) is a prevalent congenital cardiac anomaly associated with a persistent opening between the atrial septum, allowing communication between the left and right atria. Despite often being asymptomatic, PFO can lead to various clinical presentations, including cryptogenic stroke and other embolic events. Transient visual disturbances, alterations in the visual field, migraine with aura, impaired eye movement and endogenous eye infections may prompt patients to seek ophthalmological consultation. […] Despite often being asymptomatic, PFO has been associated with various clinical presentations, ranging from cryptogenic stroke to different embolic events. […] These symptoms could include transient visual disturbances, alterations in the visual field, migraine and other oculomotor signs that raise suspicion of possible PFO-related complications.

  A patent foramen ovale (PFO) is a small, flap-like opening between the right and left atrium of the heart. It is the most common heart abnormality of fetal origin present in approximately 25% of the worldwide adult population. Historically, PFOs are associated with increased stroke risk due to the paradoxical embolism of venous thrombi that shunt through the PFO directly to the oxygenated left atrium. […] A 48-year-old African American female presented with a history of two incidents of transient vision loss of the left eye. In both instances, she stated she experienced a darkness over the left eye that lasted about 15 minutes before self-resolution. Following both incidents, she reported a transient tingling sensation on the left side of her body. […] Through consultation with cardiology, it was determined her transient vision loss was a result of paradoxical embolism via PFO, and the patient was scheduled for PFO closure surgery.

[…] Transient ischemic attack (TIA) or mini-stroke that impairs your ability to move your arms or legs, and affects vital organs such as the brain, small intestine, large intestine (colon) or kidneys. […] Many children with PFO find the flap seals completely on its own during their first three years. Many people who still have PFO as adults lead long, full lives. […] Patent foramen ovale (PFO) is a small communication between the upper right and left chambers of your heart. PFO affects about 25% of people. PFO often doesnt cause any symptoms and may not require treatment. But it can sometimes indicate stroke or mini-stroke.

  Infants with a PFO and no other heart defects do not have symptoms. Some adults with PFOs also suffer from migraine headaches. […] This condition is not treated unless there are other heart problems, symptoms, or if the person had a stroke caused by a blood clot to the brain. […] Rarely, people with PFOs may have a higher rate of a certain type of stroke (called paradoxical thromboembolic stroke). In a paradoxical stroke, a blood clot that develops in a vein (often leg veins) breaks free and travels to the right side of the heart. Normally, this clot would then continue to the lungs, but in someone with a PFO, the clot could pass through the hole to the left side of the heart. It may then be pumped out to the body, travel to the brain and become stuck there, preventing blood flow to that part of the brain (stroke). […] Having a very mobile septum along with a PFO may lead to a higher risk for having a stroke.

[…] Migraine or migraine-like symptoms – Whether symptoms are due to transient ischemic attacks or paradoxical embolism is not clear. […] Neurologic decompression sickness – Seen with PFO in a small percent of scuba divers. […] Other, less common clinical manifestations of PFO include the following: […] Acute myocardial infarction. […] Systemic embolism, such as renal infarction. […] Fat embolism. […] Paradoxical embolism caused by right atrial tumors that increase right atrial pressure. […] Left-sided valve disease in carcinoid syndrome. […] With increasing evidence that PFO is the culprit in paradoxical embolic events, the relative importance of the anomaly is being reevaluated. […] Any conditions that increase right atrial pressure more than left atrial pressure can induce paradoxical flow and may result in an embolic event. […] This reasoning has greatly altered the previous conception of PFO and has changed management of the condition.

  This case highlights the importance of understanding ocular symptoms in the setting of cardiac pathology. […] If symptomatic, the risk of low oxygen levels, blood clots, or strokes rises and treatment is considered. […] The cardiology service ran a transthoracic echocardiogram which showed overall normal systolic function with no evidence of pulmonary hypertension. However, bubble study revealed a patent foramen ovale with right-to-left passage of saline contrast with release on valsalva. According to cardiology, the transient vision loss was likely from a paradoxical embolus from PFO.

  https://www.ncbi.nlm.nih.gov/books/NBK493151/

  Patent foramen ovale (PFO) occurs when a remnant of normal fetal anatomy abnormally persists into adulthood. If PFO persists into adulthood, it usually leads to right-to-left shunting of deoxygenated blood, which can be symptomatic or asymptomatic. Most adult patients with a PFO are asymptomatic; however, in some adults, PFO may result in an inter-atrial, right-to-left shunting of deoxygenated blood and the potential for shunting venous thromboembolism to the arterial circulation. The majority of patients with PFO are asymptomatic. However, some may present with severe clinical symptoms like migraines-like headaches, symptoms, and signs of ischemic brain stroke or a transient ischemic event to any of the vital organs (brain, limb, kidneys, intestine, etc). In neonates and children, the prognosis of PFO is excellent, and PFO usually closes in most of them. For those children and adults who require surgical closure due to thromboembolism risks, the prognosis is favorable.

  Patients with a Patent Foramen Ovale (PFO) usually dont show any symptoms, but in some cases, it can lead to serious problems. These can include severe headaches similar to migraines, symptoms related to decreased blood flow to the brain or other essential organs like the arms, legs, kidneys, or intestines. This reduced blood flow can cause a stroke-like event. Some of the less common symptoms can be a blood clot that moves to another part of the body, a heart attack, a blockage of an artery in another part of the body, or shortness of breath when at rest. The physical examination usually doesnt indicate any unusual findings. Occasionally, a soft whooshing sound, known as a faint systolic murmur, might be heard during the heartbeat due to abnormal blood flow. […] The prognosis for Patent Foramen Ovale (PFO) is generally very good in newborns and children, as the hole often closes on its own. For older children and adults who need surgery to close the hole due to the risk of blood clots, the outlook is also positive, and the success of these surgeries has been well-documented. There is also a non-surgical procedure called percutaneous closure that shows promise but can come with complications such as blood clots, device movement, and incomplete closure.
