Patent Foramen Ovale (PFO) Closure

    Overview

    If you have experienced a stroke with no clear cause, your doctor may have mentioned something called a patent foramen ovale (PFO). A PFO is a small, flap-like opening between the upper chambers of your heart (the left and right atria) that did not close properly after birth. For most people, a PFO does not cause any issues, but in some cases, it can allow small blood clots to bypass the lungs and travel to the brain, increasing the risk of a stroke or transient ischemic attack (TIA).

    If your doctor determines that your stroke might be linked to a PFO, close this opening could help reduce the risk of future strokes.

    What is PFO Closure?

    PFO closure is a minimally invasive procedure that seals the small opening in your heart. By closing the PFO, the risk of clots traveling to your brain is significantly reduced. This procedure is recommended for people who have had a stroke with no other identifiable cause.

    During the procedure

    A specialized cardiologist performs PFO closure using a catheter-based technique:

    1. Accessing the heart: A thin tube (catheter) is inserted into a vein in the leg and guided to the heart.
    2. Placing the device: Using advanced imaging, the doctor places a small, umbrella-like device at the site of the PFO. This device acts as a plug, closing the opening between the heart chambers.
    3. Healing: Over time, the heart tissue grows over the device, making it a permanent part of the heart.

    The procedure typically takes about an hour, and most patients can go home the next day.

    Who should consider PFO Closure?

    PFO closure may be right for you if:

    • You have had a stroke with no other identified cause.
    • Testing has confirmed the presence of a PFO.
    • Your doctor believes your stroke may have been caused by a blood clot passing through the PFO.

    Life after PFO Closure

    • Recovery: Most people return to normal activities within a few days. You may need to avoid heavy lifting for a couple of weeks.
    • Medications: You may need to take blood-thinning medications for a few months to help prevent clots while the device settles.
    • Follow-up: Regular check-ups and imaging tests will ensure the PFO is fully closed and the device is functioning properly.
