Looking for Stroke Patients over 70 who had a PFO Closure.

This past April I had a blood clot in my left posterior lobe resulting in a stroke. I'm 78 but with no obvious condition for generating the clot. My cardiologist conducted a transesophageal echocardiogram and found a PFO or hole between my upper chambers of my heart. He referred me to a specialized at the cardiology department for the Oregon Health Science University specialist and a neurologist to determine if the hole should be closed. The information that I've read about PFO Closures indicate it will reduce the chance of a 2nd stroke, but patients over 60 have a chance of getting Afib.
My neurologist and cardiologist specialist are waffling about whether it should be done. The cardiologist wanted the neurologist to make the decision. The neurologist initially decided we should proceed and we sent December 13 for the procedure. She is now not sure if we should do it and treat it with medication. She hasn't been able to discuss it with the cardiologist.
In the meantime, I'm trying to gather additional information regarding how well the procedure has worked with people closer to my age. I've been part of another forum on prostrate cancer and have learned a lot from other people going through the same condition that I had. I thought this forum might have others who also are going through my same experience and can share their experiences and advise.
I look forward to hearing from others and hope they are having successful recoveries.
