Can Having A Patent Foramen Ovale Cause Permanent Damage To The Heart
No: A patent foramen oval is present in up to 1/3 of the population. Their presence does not cause damage to the heart. ...Read more
Foramen ovale is one of the physiological shunts in the fetal heart between right and left atrium. It closes shortly after newborn period, when systemic blood pressure rises and takes over the pulmonary pressure and aorta begins to supply the majority of the body with the more oxygenated blood from the left ventricle, in contrast to the fetal circulation, where main blood supply ...Read more
NO: A pfo is a small communication between the two upper chambers of the heart and usually it does not cause a murmur. Now if the hole is bigger it may be an atrial septal defect (ASD) which would cause a murmur. So unless it's an ASD and erroneously called a pfo, it should not cause a murmur. ...Read more
My son (age 15) just had a physical and a heart mumur - he had a electrocardiogram and found patent foramen ovale - should he have surgery to close?
A patent formen ovale is usually asymptomatic and does not require treatment, however, the issue needs to be assessed by a cardiologist to ensure that there is no other cardiac anomaly. See this site for more information.

ASD=RV volume load: This may be a matter of semantics/terminology. Sometimes, patients with an atrial septal defect (ASD) are labeled as having a patent foramen ovale, as both lesions occur in the same spot. If there is an asd, there can be sufficient left-to-right shunting at the atrial level, resulting in rv volume overload, rv enlargement and rv hypertrophy. ...Read more
D I had a stroke two years ago and today is clear that it was caused by patent foramen ovale. Can I keep doing sports like swimming, running, fitness?
Probably: First, we can rarely guarantee that a stroke is caused by a pfo--20-25% of the general population has a pfo, which means that anyone who has a stroke for any reason has a 20% chance of having a pfo. That being said, the younger and healthier a patient is, the more likely it is that the pfo was related to stroke. There is no contraindication to exercise with pfo. Check with your doctor to be sure. ...Read more
Could Patent Foramen Ovale be easily detected by the Echocardiogram technician? I ask this as i’ve had 4 Echocrdigrams after Mitral Prolapse, and Mitral valve repair. I have 40 Migraine Auras a yr and looking for the cause My cousin has this condition.
Patency (opening) may NOT show up in ultrasound studies!
Hope this is helpful!

Would you expect people suffering from frequent migraine without the aura to possibly have a patent foramen ovale (PFO)?
Most people have a tricuspid valve that leaks a little. It can be completely normal and leak.
We can use the velocity of the leak to estimate the pressure in the right ventricle (rv) the rv pressure should be low, approx. 1/4 to 1/3 of the normal BP measured by a arm blood pressure cuff.
A pfo is a structural hole that everyone has as a newborn and usually closes.
No real relationship. ...Read more
Different: Patent foramen ovale is a temporary natural opening between two atria that allows fetal circulation to occur. Once born it closes spontaneously. An atrial septal defect is an abnormal opening between two atria that occurs due to incomplete formation of the atrial wall. It does not close spontaneously usually and may need surgery if it causes significant flow issues. ...Read more
How is an emboli able to traverse a patent foramen ovale if the net flow of blood is from left to right atrium?
Possible: The heart is a pump and a dynamic process. The net pressure is from high to low. But invariably with activity motion and changing in position the flow can switch transiently. If a clot is in the flow at that time then it can become an arterial emboli with all its consequences. ...Read more
Please help! What is the relationship between tricuspid regurgitation and a patent foramen ovale?
None: I assume that you had an echocardiogram. Tricuspid regurgitation is commonly seen on echocardiography. Most of the time, this is a normal finding and not indicative of disease. The velocity of the tr jet can be useful to measure to estimate right ventricular pressure. Pfo is also commonly seen, and not necessarily indicative of disease. More information is needed to provide more insight. ...Read more
Common: All infants have a patent foramen ovale (pfo) as a fetus. This allows the fetal circulation to flow. Once born the pfo will close as the concentratiojn of oxygen in the blood rises. In a small percentage of infants the pfo may persist. Figures on this occurrence vary from 10-15%. Rarely is any treatment required unless the blood flow is severely affected. Most close within 1-2 years of birth. ...Read more
Mostly benign: This is a small window between the upper heart chambers that is usually blocked off after birth. When baby starts to breathe, the circulation changes, increasing pressure that closes a flap over this window. It can still open if pressures in the upper chambers allow it. Very rarely, a person can pass a clot though that point and trigger a stroke. For most of us, it is of no functional importance. ...Read more
Yes: Good followup with your cardiologist should be continued. ...Read more
A normal duration: The presence of a patent foramen ovale has not been shown to affect life expectancy in the general population. ...Read more
Is it possible for a child to have a patent foramen ovale (pfo) and a patent ductis arteriosus (pda)?
Yes: It is a normal feature of the heart prior to birth and may persist in some. The PDA is usually picked up on exam, the pfo would only be accessible to advanced studies. ...Read more
Can you give me more info on experience with a child who has a patent foramen ovale (pfo) and a patent ductis arteriosus (pda)?
Common: All normal fetuses have a pfo and a pda. These are connections between the "left heart" and the "right heart" that allow blood to bypass the lungs and flow properly to the placenta. Typically, in the first 24 hours after birth, the PDA closes. Pfo closure can be more gradual and can be present for many months, and still be a normal finding. Persistent patency can be a problem. ...Read more
Small heart opening: It is an opening in the wall between the upper chambers of the heart that allows blood from the placenta to get to where it needs to go during fetal life. All babies are born with this. It usually closes after birth, but 20% of all adults still have this. It is normal, though it has been associated with stroke, migraine headach, and decompression illness in scuba divers. ...Read more
A hole in the heart: A patent foramen ovale (pfo) is a necessary hole between two upper chambers of the heart. This hole allows fetal blood circulation to occurr. Once the baby is born, circulation changes, the hole closes to allow normal post natal human circulatuin pathway. It remains open in a small number of patients and is usually asymptomatic. ...Read more
Surgery: Most patent foramen ovales (pfo) do not have to be repaired. However if repair is indicated due to failure or respiratory issues, it would require open median sternotomy and probably 5-6 days in the hospital. This of course depends on the age of the patient. ...Read more
Catheter based: A PFO is usually repaired with a heart catheterization. An occluding device is delivered with a catheter from the leg and placed in the pfo. Closure is usually 100% effective. ...Read more
When it's big: Most foramen ovale close after a baby is born, however sometimes it does not close. If a person has heart problem, pictures are taken a patent foramen may be discovered. If the pfo is contributing to a heart problem it may be closed, however many are discovered only after a person dies of other causes and happens to have autopsy, in other words people likely have them and they don't effect them. ...Read more
Yes: A patent foramen ovale (pfo) and patent ductus arteriosus (pda) are conditions that allow fetal circulation to flow. Once the infant is born different blood flow patterns are required to oxygenate the blood. The closing off of the pfo and PDA allow the blood flow to assume the normal post natal pattern. ...Read more
In a Sense: A pfo should not cause--or contribute to the development of pulmonary hypertension. However, a pfo in people with pulmonary hypertension can be an issue. The pfo can be a potential means for a blood clot to cross the heart and travel to the brain rather than the lungs. This is rare, and depends on other medical conditions. Please discuss your specific issues with your doctor. ...Read more
