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.
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.
After adjustment for other stroke risk factors, PFO remained strongly associated with cryptogenic stroke in both the younger (odds ratio 3.70, 95% confidence interval 1.42 to 9.65; p=0.008) and the older group (odds ratio 3.00, 95% confidence interval 1.73 to 5.23; p<0.001)24.
PFO can occasionally result in complications. The most serious of these is stroke. Most people will not need treatment for a PFO. Some people receive treatment for PFO, especially if they have had a stroke due to a PFO.
Most people will not have any signs or symptoms directly from PFO at all. Possible PFO symptoms include: Stroke. Transient ischemic attack (TIA) or mini-stroke that impairs your ability to move your arms or legs, and affects vital organs such as the brain, small intestine, large intestine (colon) or kidneys.
