Patent Foramen Ovale (PFO) Closure

About
What is the Patent Foramen Ovale (PFO) Closure Procedure?
A Patent Foramen Ovale (PFO) is a small, congenital opening between the heart’s upper chambers (atria) that can allow blood clots to bypass the lungs and potentially cause strokes. The Patent Foramen Ovale (PFO) closure procedure is a minimally invasive technique in which a closure device is delivered through a catheter inserted via the femoral vein in the groin to seal this opening. PFO closure may reduce the risk of recurrent stroke in selected patients where no clear cause of stroke has been found; most still need some medication.

How It's Done
How Is Patent Foramen Ovale (PFO) Closure Done?
A small incision is made in the femoral vein in your groin.
A thin catheter with a deflated balloon is inserted through the incision and guided toward the heart using live X-ray or ultrasound imaging.
The balloon is briefly inflated to measure the size of the opening.
A specially designed Patent Foramen Ovale (PFO) closure device is delivered through the catheter and positioned at the hole.
The device is released to seal the Patent Foramen Ovale (PFO) permanently, allowing heart tissue to grow over it naturally.
The catheter is removed, and the incision is closed with a stitch or bandage.
Who it’s for?
Who Needs Patent Foramen Ovale (PFO) Closure?
Patent Foramen Ovale (PFO) closure is considered only for patients who have a confirmed Patent Foramen Ovale (PFO) and meet one or more of the following criteria:
Had a stroke or Transient Ischemic Attack (mini-stroke) with no clear cause.
Evaluated for cryptogenic stroke during bubble contrast study or pressure testing, where Patent Foramen Ovale (PFO) is found as a contributing factor
PFO closure may be considered in adults who have had a stroke with no other clear cause and who have a PFO with higher risk features, usually between the ages of 18 and 60. Your cardiologist and neurologist decide whether it suits you.
Have an atrial septal aneurysm.
Have migraines with aura.
Experienced a paradoxical embolism or decompression illness.
Are at risk of blood clots.
Prefer a one-time procedure instead of long-term blood thinners
Want to prevent future strokes without ongoing medication
