Patent foramen ovale (PFO) is an opening in the upper chambers of the heart due to a flap of tissue that failed to close normally after a baby is born. There is no known cause, and there are usually no symptoms associated with PFO.
Treatment is not necessary in most PFO cases. Babies born with PFO and no other heart conditions are not considered to have an abnormal heart condition. Older adults with PFOs may have a higher risk of a certain type of stroke called a paradoxical thromboembolic stroke.
Patent Foramen Ovale Treatment at RUSH
An imaging test called an echocardiogram can be used to diagnose a PFO.
The condition, however, doesn't require treatment unless you have other heart problems or recurrent, unexplained strokes. If you've had a stroke and you have a PFO, RUSH is one of only a few health systems in the U.S. conducting research on closing such defects.
If you need treatment, a highly trained heart expert at RUSH will likely close the PFO using a procedure called cardiac catheterization.
Catheterization avoids the need for the chest to be opened. A thin, flexible tube called a catheter is threaded to the heart through a blood vessel in the arm, upper thigh or neck.
