A patent foramen ovale (PFO) is a hole in the heart that didn't close the way it should after birth. The hole is a small flaplike opening between the upper heart chambers. The upper chambers of the heart are called the atria.
PFO itself usually does not cause any symptoms. PFO can occasionally result in complications. The most serious of these is stroke. Most people will not need treatment for a PFO.
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 .
2) The foramen magnum is the opening in the bottom of the skull through which the spinal cord exits. "Widely patent" means that is is of normal size. 3) This term means there is a bit of extra bone growth around the openings in the spinal column through which the nerve roots from the spinal cord emerge.
PFO is common, presenting in about one in four people. But more than 95% of those with the condition will never find out, as most don't suffer PFO symptoms or health issues. Heart specialists don't often need to diagnose or treat PFO in healthy patients.
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.
