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.
The 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.
Some times the foramen ovale does not get closed soon after the birth. This condition is called as patent foramen ovale.
The Foramen Ovale gives rise to the Fossa Ovalis. In most individuals, the foramen ovale closes at birth. It later forms the fossa ovalis.
There is the hole between two atria in the fetus. That is called as foramen ovale. You have one foramen ovale at the base of the skull. Mandibular nerve passes through this foramen ovale.
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:

Some times the foramen ovale does not get closed soon after the birth. This condition is called as patent foramen ovale.
745.5 A patent foramen ovale (PFO) is a hole in the heart that didn't close the way it should after birth.
Acleistocardia is the inability of the foramen ovale of the heart to close properly.
fossa ovalis
The Foramen Ovale gives rise to the Fossa Ovalis. In most individuals, the foramen ovale closes at birth. It later forms the 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.
A patent foramen ovale is when a flap that is open while in the mothers wound does not close. They do not usually enlarge.
There is the hole between two atria in the fetus. That is called as foramen ovale. You have one foramen ovale at the base of the skull. Mandibular nerve passes through this foramen ovale.
The ductus arteriosus and foramen ovale are important for systemic circulation. This is the type of circulation maintained by fetal pigs but the adult heart requires pulmonary and systemic circulation.
