A hole in your heart would seem to be the very definition of a "problem." Yet more than a quarter of the population has one, and for most it causes no adverse health effects. A foramen ovale is a hole in the heart. The small hole naturally exists in babies who are still in the womb for fetal circulation. It should close soon after birth.

Overview. A patent foramen ovale (PFO) is a hole in the heart that didn't close the way it should after birth.

What is a Patent Foramen Ovale? A patent foramen ovale (PFO) means the foramen ovale did not close properly at birth, so there is still an opening in the septum. In most cases, the PFO does not stay open at all times. Instead, it’s more like a flap that opens when there is higher pressure than normal in the chambers on the right side of the.
In fact, since PFO’s are so common, the detection of a PFO in an adult is usually incidental, i.e. has nothing to do with causing any problem. PFO’s do not cause chest pain, heart palpitations, or heart failure. PFO’s typically do not disrupt heart function and people are able to exercise and carry out all activities normally. Adult Congenital Heart Disease; Treatments; ASD and PFO Closures A patent foramen ovale (PFO) occurs when the foramen ovale does not seal after birth. The foramen ovale is a natural shunt (channel) that allows blood to enter the left atrium from the right atrium. In most people, the foramen ovale closes within a year of birth.
