20% Humans have hole in their Heart - Patent Foramen Ovale (PFO)

Foramen Ovale is a medical condition found in most of the newly born babies. In this medical condition there is a hole between the upper chamber of heart (i.e. right and left auricle). It is a common phenomena in babies. But this hole is closed automatically within a few weeks after birth. But one in every five person is not so lucky and his/her Foramen Ovale remain open. This medical condition is called Patent Foramen Ovale (PFO), also known as Atrial septal defect.

What happens to our body due to Patent Foramen Ovale (PFO) ?
Our right auricle contains the deoxygenated blood while left auricle contains the oxygenated blood. The hole between these two chambers of heart mixes the pure blood with impure blood. The same blood is then sent to different body parts and the same mixed blood is sent to lungs to get oxygenated. No major symptoms can be noticed of this medical condition in childhood. But as the person reaches 30's some symptoms become visible. These symptoms are:

Why do newly born babies have Foramen Ovale ?
When the arteries and veins develop in a baby inside the womb of her mother it needs blood supply. The hole (Foramen Ovale) provides more blood instantly to the heart to pump into these newly developed arteries. This Foramen Ovale does not cause any harm to baby as at that time lungs of mother are oxygenating the blood for baby. Baby's own lungs don't oxygenate the blood as baby can't breathe in the womb. As the baby is born the Foramen Ovale closes itself within a few weeks.
