What is the closure time of foramen ovale

summary

There will be a magical hole in the body of the newborn fetus, called the foramen ovale, which everyone will have. And it will close slowly. Many people don't know much about the closure time of foramen ovale. Let's introduce the closure time of foramen ovale.

What is the closure time of foramen ovale

First: in human fetus, there is a small hole in the left and right atrial septum, which makes the blood between the left and right atrium communicate. Later, when the pulmonary circulation was completed, the orifice was closed. This is the trace left by the development of human history, which will disappear with the growth of children.

Second, foramen ovale is an open area in the middle of atrial septum, which is located at the junction of primary septum and secondary septum. The foramen ovale is usually covered by a thin section of the primary septum. Before birth, as the blood flow is from right to left, the foramen ovale continues to open. And then it will close slowly.

Third, the foramen ovale is located in the middle and upper part of the atrial septum and is open in the fetus. Generally, newborns are closed 5-7 months after birth. If there is no closure after 7 months, it is called "patent foramen ovale", which is a kind of congenital heart disease. Timely treatment is needed.

matters needing attention

The closure time of foramen ovale is not necessarily accurate for each baby, which varies from person to person, but generally speaking, the difference between each person is not very big. If it is a long time to close, you need to see a doctor.
