FAQ
``In simplistic terms, a PFO is the result of incomplete closure of atrial tissue, whereas an ASD is the result of complete absence of such tissue between the right and left atrial heart chambers.''
Definition. Patent foramen ovale (PFO) is a hole between the left and right atria (upper chambers) of the heart. This hole exists in everyone before birth, but most often closes shortly after being born. PFO is what the hole is called when it fails to close naturally after a baby is born.
PFO was found in 25 to 30 percent of individuals in an autopsy study and in a community-based transesophageal echocardiography (TEE) study 4,5.
When a baby's lungs begin working, blood flow through the heart changes. Now the oxygen-rich blood comes from the lungs and enters the left upper heart chamber. The pressure of the blood pumping through the heart usually forces the flap opening of the foramen ovale to close.
Healthcare providers don't know what causes the hole to stay open (patent) in some people instead of closing up. Sometimes, PFO occurs along with other heart problems. One such condition is Ebstein anomaly. It's when the valve between the upper and lower chambers on the right side of the heart doesn't close properly.
Patent foramen ovale (PFO) is when you have a small flap or opening between the upper right and left chambers (atria) of your heart. Everyone has this opening, called a foramen ovale, before birth. In most people, this closes after birth. Patent foramen ovale occurs when the flap still exists after birth.
Having a PFO as an adult or older child is not normal. But it occurs in many people. It may be slightly more common in younger adults compared with older adults.
During the procedure, an interventional cardiologist: Makes a tiny incision in your groin and inserts a catheter into a blood vessel. Uses ultrasound imaging to get a closer view of the PFO. May guide a deflated balloon through the catheter and move it to the PFO.
Ingly, the PFO can be classified as large ( 4 mm), medium (3.9–2 mm), and small (<2 mm).
Small holes between the upper chambers of the heart may be categorized as an atrial septal defect (ASD) or patent foramen ovale (PFO). An ASD is a congenital heart defect, a condition that you are born with. PFOs can occur only after birth when the foramen ovale fails to close.
