How Long Can I Live With A Patent Foramen Ovale If It Was Never Corrected
...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
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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
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
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
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
Is it possible for a child to have a patent foramen ovale (pfo) and a patent ductis arteriosus (pda)?
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
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
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 moreSee 1 more doctor answer
