Just curious but how many others out there have been diagnosed as having a PFO? I had a transcranial doppler bubble echo test and it revealed a PFO. I also suffer from persistent visual symptoms of visual snow and mild ghosting or distortion (extremely hard to discribe but all I can tell you is that my vision is messed up). Oh ya and don't forget the constant tension headaches. I have read some studies that say PFO is linked to migraine/migraine aura and was wondering if getting the hole plugged up would be worth it. If it reduces my vision symptoms as well as reducing my chances of stroke that would be super.
