Patent Foramen Ovale With Left To Right Shunt
PFO: The patent foramen ovale (PFO) is a small communication between the right and left upper chambers of your heart. It is needed for oxygenation when you're fetus. Sometimes it doesn't close. It is thought to be present in ~20 to 30% of the population. The shunt means they can see the passage of blood through it. This small hole is inconsequential and USUALLY requires no further testing or treatment. ...Read moreSee 1 more doctor answer
...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
Hi doctors, can you tell me what does "small patent foramen ovale with noted bidirectional shunt" mean?
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
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 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
