Can having a patent foramen ovale cause permanent damage to the heart?

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 (Definition)

...In newborns, it allows proper circulation in the fetus by shunting blood coming from the mother's placenta to the left side of the baby's heart, which is pumped immediately out to the body. Nearly all infants have this structure still open when they are born, which usually close within weeks to months after birth. A small percentage of adults still can have an ...Read more

Does a PFO (patent foramen ovale) ever cause a heart murmur?

Does a PFO (patent foramen ovale) ever cause a heart murmur?

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?

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?

Depends: 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. Http://www. Ncbi. Nlm. Nih. Gov/pubmedhealth/pmh0002102/. ...Read more

Does patent foramen ovale cause right ventricular hypertrophy? If so why?

Does patent foramen ovale cause right ventricular hypertrophy? If so why?

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

What is the relationship between tricuspid and a patent foramen ovale?

What is the relationship between tricuspid and a patent foramen ovale?

Proximity: Tricuspid valve is the valve controlling blood flow from right atrium to the right ventricle. Patent foramen ovale is a temporary opening between the right and left atrium that allows neonatal circulation. It closes after birth. ...Read more

What is the relationship between having tricuspid regurgitation and a patent foramen ovale?

Tricuspid Regurg.: 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

When is surgery needed for a child with a? Patent foramen ovale? And a patent ductis arteriosus?

When is surgery needed for a child with a? Patent foramen ovale? And a patent ductis arteriosus?

With symptoms: In the majority of cases these openings close spontaneously shortly after birth. When they remain open and interfere with adequate oxygenation and/or ventilation, exercise tolerance, etc., then surgery may be indicated. Surgery can be done minimally invasive or open. ...Read more

What is the difference between a patent foramen ovale and atrial septum defect?

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?

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

How common is a patent foramen ovale?

How common is a patent foramen ovale?

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

How serious a condition is a patent foramen ovale?

How serious a condition is a patent foramen ovale?

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

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

What's a patent foramen ovale?

What's a patent foramen ovale?

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

What is a patent foramen ovale?

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
