When does the oval hole close?

The foramen ovale

is a physiological structure that provides oxygen to the fetus in the womb. It is a small hole between the two atria, located in the upper part of the atria. Normally, the foramen ovale should close within a few days or weeks after birth. The specific closing time varies from individual to individual, but it usually closes within one year after birth.

The closure of the foramen ovale symbolizes changes in the respiratory system and the development of the heart structure of the newborn. If it does not close after 1 year of age, it is necessary to seek medical advice.
