You may be asleep for the procedure, or you may get a sedative to help you relax. Your doctor makes a small cut in your groin. Then the catheter, with tools inside it, is put into your blood vessel and carefully guided to your heart. Your doctor moves the tip of the catheter to place a small device inside the PFO.
Usually, patent foramen ovale causes no problems. But PFO may let a blood clot travel from the right to the left side of your heart. Your heart could pump the clot into your body. If the clot reaches your brain, it could cut off the blood supply.
Don't take a bath or swim for 1 week, or until your doctor tells you it is okay. Watch for bleeding from the site. A small amount of blood (up to the size of a quarter) on the bandage can be normal. If you are bleeding, lie down and press on the area for 15 minutes to try to make it stop.
Treatment. This condition is not treated unless there are other heart problems, symptoms, or if the person had a stroke caused by a blood clot to the brain. Treatment most often requires a procedure called cardiac catheterization, which is performed by a trained cardiologist to permanently seal the PFO.
If you have a PFO larger than 25 millimeters, a provider will probably do PFO closure surgery instead of using the catheter method.
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.
How is patent foramen ovale treated? Antiplatelet medicines such as aspirin, to help prevent blood clots. Anticoagulant medicines such as warfarin, to help prevent blood clots. Closure of the PFO with a catheter-based procedure. Closure of the PFO during heart surgery.
After discovering my PFO, two neurologists and the interventional cardiologist overseeing my care recommended I stop all moderate and vigorous intensity physical activities. My care team also advised me to refrain from heavy lifting or other activities that could elicit a Valsalva and induce right-to-left shunting.
Treatment most often requires a procedure called cardiac catheterization, which is performed by a trained cardiologist to permanently seal the PFO.
Some people may need a patent foramen ovale (PFO) closure, a minimally invasive procedure. This can reduce their risk of stroke. After the procedure, you may need to take antiplatelets for a few months or even for life (if you have a stroke history). Rarely, people need surgery to remove the atrial septal aneurysm.
