With pressure diminution of the right atrium due to the resistance drop in the pulmonary circulation at the first breath, the left-sided septum primum will be pressed against the right-sided septum secundum, closing the foramen ovale. The two septa will normally fuse during the first year of life.
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 .
Everyone has a PFO at birth. It is a normal part of the circulation of a fetus. But, in most infants, this small hole naturally closes very soon after birth. But in some cases, it does not.
Treatment. This condition is not treated unless there are other heart problems, symptoms, or if the person had a stroke caused by a blood clot to the brain. Treatment most often requires a procedure called cardiac catheterization, which is performed by a trained cardiologist to permanently seal the PFO.

The catheter tip has a device to plug the PFO . Surgical closure. In this heart surgery, the surgeon uses stitches to close the PFO .
If closure is required, cardiac catheterization can be used to place a device through a long, thin tube guided through blood vessels to the heart to close the foramen ovale.
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.
If you were born with a hole in your heart that never closed, known as a patent foramen ovale (PFO), you may need a procedure to correct it. Penn Medicine cardiologists use interventional techniques to close a patent foramen ovale without opening your chest for surgery.
Within a few days of receiving a PFO closure device, your body's own tissue will start to grow over and around it. Three to six months later, your heart tissue completely covers the device.
