Patent foramen ovale and migraine

It has long been thought that patent foramen ovale generally does not cause shunting between the two chambers and has no effect on the hemodynamics of the heart, and is therefore considered insignificant
.
But this is a common misconception
about patent foramen ovale.
The foramen ovale must be closed after the birth of the child
.
Let the editor introduce it to you in detail!

At birth, with the first cry, the pressure in the left atrium increases, and the oval fossa valve is pressed on the edge of the oval fossa to form a functional closure, and the anatomical complete closure generally does not last until 5-7 months
after birth.
Therefore, it is possible to remain open within one year of age, there may be a small amount of shunting, and even 5%-10% of people oval foramen remain open and not closed for life, but there is no effect
on the hemodynamics of the heart.
Therefore, patent foramen ovale in infancy is a normal physiological phenomenon, not congenital heart disease, and generally does not require surgery
.

However, if the defect in the center of the atrial septum is large, greater than 8-10 mm, and the flow is large, it is called a central atrial septal defect and needs to be repaired
surgically.

The timing of surgery should be completed
when the child is 2-4 years old.

The foramen ovale is generally closed in the first year after birth, if the foramen ovale is still not closed in children older than 3 years old, it is called patent foramen ovale, and 20%~25% of the foramen ovale in adults is not completely closed
.

Patent foramen ovale is currently the most common congenital heart abnormality in adults, and can be detected in about 1 in 4 people in the normal population
.

If the foramen ovale is still not closed in children older than 3 years old, it is called patent foramen ovale, and 20%~25% of the foramen ovale in adults is not completely closed
