Hi, Kekoa, and welcome to the forum!
I hope all goes well for you on Friday and that you have a speedy recovery.
The reason why your PFO procedure was approved without any problems is because you have already suffered a stroke. It's when people haven't had a stroke that they may have issues here in the US (not in other countries from what I have read).
There are a couple of other scuba divers that have recently posted here. I don't know if you have read their posts. I think the thread is called, "After 2 bubble echo's my large PFO..." and was started by s2k.
Take care and I hope you will keep us posted.
