Because these trials enrolled relatively young (<60 years) patients, the current American Academy of Neurology guidelines recommend PFO closure in stroke patients who are <60 years old 4.
Are You a Candidate for PFO Closure? You may be a candidate for minimally invasive PFO closure if you: Have been diagnosed with a PFO and have had a stroke due to an unknown cause (one not attributed to a condition such as atrial fibrillation or carotid artery disease)
PFO can occasionally result in complications. The most serious of these is stroke. Most people will not need treatment for a PFO. Some people receive treatment for PFO, especially if they have had a stroke due to a PFO.
The position of our societies is to perform percutaneous closure of a PFO in carefully selected patients aged from 18 to 65 years with a confirmed cryptogenic stroke, TIA, or systemic embolism and an estimated high probability of a causal role of the PFO as assessed by clinical, anatomical, and imaging features.
If you were born with a hole in your heart that never closed, known as a patent foramen ovale (PFO), you may need a procedure to correct it. Penn Medicine cardiologists use interventional techniques to close a patent foramen ovale without opening your chest for surgery.
Alternatively, contrast-enhanced transcranial Doppler (bubble-TCD) is a non-invasive, bedside, repeatable technique with high sensitivity and specificity for PFO detection in younger patients (≤60 years) and controls,13 through identification of right-to-left shunt (RLS).
A healthcare provider may recommend a PFO closure procedure if: You've had a transient ischemic attack (TIA) more than once. You've had cryptogenic (from an unknown cause) strokes more than once. You have a low level of oxygen in your blood.
People who do not respond to medication may need a minimally invasive, catheter-based procedure. Your interventional cardiologist closes the PFO with a small closure device. This is done in a cardiac catheterization (cath) laboratory.
During the procedure, an interventional cardiologist: Makes a tiny incision in your groin and inserts a catheter into a blood vessel. Uses ultrasound imaging to get a closer view of the PFO. May guide a deflated balloon through the catheter and move it to the PFO.
