Overview
While a baby grows in the womb, there is a normal opening between the left and right atria (upper chambers) of the heart. If this opening fails to close naturally soon after the baby is born, the hole is called patent foramen ovale (PFO). {{#ev:youtube|qkh-7UbJ0GM}}
What are the symptoms of Patent foramen ovale?
Infants with a patent foramen ovale and no other heart defects usually do not have symptoms.
What causes Patent foramen ovale?
While a fetus grows in the uterus, its lungs are not functional. The foramen ovale allows blood to bypass the lungs so it does not cause issues in the fetus. The opening is supposed to close soon after birth, but sometimes it does not. In about 1 out of 4 people, the opening never closes. If it does not, it is called a patent foramen ovale (PFO). The cause of a patent foramen ovale is unknown.
Who is at highest risk?
There are no known risk factors.
Diagnosis
An echocardiogram can be done to diagnose patent foramen ovale. If the patent foramen ovale is not easily seen, a cardiologist can perform a "bubble test." Saline solution (salt water) is injected into the body as the cardiologist watches the heart on an ultrasound (echocardiogram) monitor. If a patent foramen exists, tiny air bubbles will be seen moving from the right to left side of the heart.
When to seek urgent medical care?
Mostly patent foramen ovale stays asymptomatic. In case of development of weakness of any part of body (stroke), seek urgent care.
Treatment options
This condition is not treated unless other heart abnormalities exist or if you had a stroke caused by a blood clot to the brain. Treatment usually requires cardiac cathertization by a specifically trained cardiologist to permanently seal the PFO.

Directions to hospitals treating Patent foramen ovales
Prevention
There is no known way to prevent the defect, but some of the complications can be prevented with early detection.
What to expect (Outlook/Prognosis)?
The infant will have normal health in the absence of other heart defects.
Possible complications
Unless there are other associated defects, there are usually no complications associated with a patent foramen ovale. There have been some studies suggesting that older patients with patent foramen ovale have a higher rate of a certain type of stroke (called paradoxical thromboembolic stroke). The reason for this is that older people frequently develop blood clots in the veins in their legs. These clots can sometimes travel from their original site to the right side of their heart. If a patent foramen ovale is present, the clot can then pass from the right side to the left side and may travel to the brain and become lodged there, preventing blood flow to that part of the brain (stroke). Some patients may take medication to prevent blood clots.
