Usually, patent foramen ovale causes no problems. But PFO may let a blood clot travel from the right to the left side of your heart. Your heart could pump the clot into your body. If the clot reaches your brain, it could cut off the blood supply.
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 .
The most common indication for PFO closure was stroke/systemic embolism (58.6%) followed by TIA (10.2%) and migraine (8.8%). The other indications category included 22.4% of patients without stroke/systemic embolism/DCI, migraine, or TIA.
The cause of a PFO is unknown. There are no known risk factors.
