A small flap-like opening called the foramen ovale is in the wall between the right and left upper chambers of the heart. It is essential in the womb, but normally closes after birth. A patent foramen ovale (PFO) is a flap that didn’t close.
This is present in 15-25% of all people and is usually of no consequence. It usually doesn’t create any signs or symptoms.
