Patent Foramen Ovale (PFO) In approximately one out of every four individuals, the hole in the heart will remain open after birth. This is called a patent foramen ovale, or PFO.

However, in a small minority, a PFO may permit blood clots to pass from the right side of the heart to the left side, possibly leading to a stroke. See more
