When the foramen ovale, a small opening between the right and left atria of the heart, fails to close after birth, it can lead to a condition known as patent foramen ovale (PFO). This can allow blood to flow between the atria, potentially leading to reduced oxygen levels in the blood and an increased risk of stroke or other complications. Many individuals with a PFO remain asymptomatic, but in some cases, it may require medical intervention if it causes significant health issues.

What is it called if the foramen ovale doesn't close at birth?

If the foramen ovale doesn't close at birth, it is called a patent foramen ovale (PFO). This condition can lead to blood flow between the two upper chambers of the heart (atria), which may cause health issues such as stroke or heart failure. Treatment options include medications or a procedure to close the opening.

What is the function of the forarm ovale?

In the fetus blood flow to the lungs doesnt occur in nearly as greater volume as fetuses are suspended in fluid and dont breathe. The foramen ovale acts to shunt (move) blood into the left atrium from the right atrium, as the blood in the RA doesnt need to go to the lungs and would be of much better use going into the LA and into systemic circulation... so the foramen ovale means blood can bypass the lungs, as they are not of use in the fetus. Due to pressure changes (when the lungs inflate) at birth the foramen ovale shuts and fibroses over.


Formen ovale Ductus arteriosus Ductus venosus what will these shunts become in a newborn?

In a newborn, the foramen ovale will close and become the fossa ovalis. The ductus arteriosus will close and become the ligamentum arteriosum. The ductus venosus will close and become the ligamentum venosum.

What is patent foramen ovale?

Patent foramen ovale is a common heart condition where a small hole in the heart that typically closes after birth remains open. This opening can allow blood to bypass the lungs and mix oxygenated and deoxygenated blood, which may lead to potential health issues like a higher risk for stroke.
