Why is it important that the foraman ovale close soon after birth?

After the child is born, the umbilical cord is cut, and the child takes its first breaths, the pressure in the pulmonary vasculature decreases, decreasing the pressure gradient from the left to the right heart, thus allowing the foramen ovale to close.
the hole can be closed with a plug if its small and fixed with surgery if its large... in either case normal life can occur.

∙ 9y agoThe foramen ovale should close soon after the birth of the baby. Otherwise you get the blood flow from left atrium to right atrium. This floods the lungs to create so many problems.

What will happen if the foramen ovale does not close right after birth?
The blood will bypass the pulmonary circulation and won't become oxygenated.If the foramen ovale of the heart (there is also one in the skull) remains open (patent), blood will still be shunted between the atria and oxygen high blood will be mixed with oxygen low blood. It depends on how large the opening remains on how much effect this will cause. 10-20% of adults have this defect and show no problems.See link below:

When did the formen ovale change to fossa ovalis?
From the Wikipedia entry for "Foramen ovale (heart)": Normally this opening closes in the first year of life. When the lungs become functional at birth, the pulmonary pressure decreases and the left atrial pressure exceeds that of the right. This forces the septum primum against the septum secundum, functionally closing the foramen ovale. In time the septa eventually fuse, leaving a remnant of the foramen ovale, the fossa ovalis. In other word, it "changes" for each person shortly after that person's birth.
