An echocardiogram can be done to diagnose a PFO. If the PFO 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.
Having a PFO as an adult or older child is not normal. But it occurs in many people. It may be slightly more common in younger adults compared with older adults.

Rarely, a patent foramen ovale can cause a significant amount of blood to go around the lungs. This lowers blood oxygen levels, a condition called hypoxemia. Stroke. Sometimes small blood clots in veins may travel to the heart.
A patent foramen ovale may be difficult to confirm on a standard echocardiogram. Your provider may recommend this test to get a closer look at the heart. A transesophageal echocardiogram takes pictures of the heart from inside the body. It's considered the most accurate way to diagnose a patent foramen ovale.
Patent foramen ovale occurs when the flap still exists after birth. “Patent” means “open.” Most of the time, people with PFO don't have symptoms and won't need treatment. But some uncommon problems related to the presence of PFO include stroke and mini-stroke.
Can PFO get worse? Generally speaking, a PFO doesn't change as patients age. But other changes in the heart and the circulation may change the pressures in the heart on each side of the flap, leading to more frequent opening of the flap and wider opening of the flap.
Of 70 patients, 62 experienced spontaneous closure (89%). Figure 2. Kaplan- Meir plot of time to spontaneous closure of PFO. Spontaneous PFO closure occurred at a median age of 8 months.
In general, patent foramen ovale doesn't cause symptoms or health complications, but it can increase your risk for developing the following: Migraine headaches. Blood clots. Low oxygen levels (Platypnea orthodeoxia)
