Patent foramen ovale (PFO) is a hole between the left and right atria (upper chambers) of the heart. This hole exists in everyone before birth, but most often closes shortly after being born. PFO is what the hole is called when it fails to close naturally after a baby is born.
Procedures to close a patent foramen ovale include: Device closure. In this procedure, the provider inserts a thin, flexible tube called a catheter into a blood vessel in the groin area. The catheter tip has a device to plug the PFO . Surgical closure. In this heart surgery, the surgeon uses stitches to close the PFO .
Most PFOs don't need to be closed. Most PFOs cause no symptoms or complications. Larger PFOs may cause stroke. People with symptomatic or large PFOs may benefit from a procedure to close the hole.
