What is a PFO Closure?
A PFO is also known as a patent foramen ovale which is a hole in the heart that usually closes at birth. During fetal development, this is a small opening that is normally present in the wall between the right and left upper chambers of the heart, known as the atria. When this foramen ovale doesn’t close, it is called a patent foramen ovale, which occurs in approximately 25 percent of the population.
Most people with a patent foramen ovale do not event know they have it. Generally, a PFO does not cause complications, but in rare cases, in patients with certain conditions, it can be related to unexplained strokes and migraines.
In certain clinical situations patients qualify to have this defect closed. This is done by a catheter based intervention that is done by a cardiologist specialized in this procedure.
