Welcome to HealingWell. I am not sure I know which old posts you were reading or who Jan is ? Perhaps if you post your questions here another member may be able to help you out.
We are all here to support you.
I am going to post a link to a very long thread that is loaded with info on PFO surgery. Do read through it but remember each person is different so take away from this thread only what helps you.
Just click on the link and the thread will open up for you.
Let us know how you are doing.
