Hi Glenn, I too am a Fallot person. I recently asked my Adult Congenital cardiologist about what's the longest he has seen as far as survival. It seems that those of us who were the Guinea pigs in those early days of cardiac surgery, are still writing the book. There are patients in their seventies now. I myself, will be 71 in June. Not bad for someone who would have most certainly died without my surgeries.
I must tell you though, you must be followed with a good congenital cardiologist. It is foolhardy not to.
Good luck to you and remember that this group is always here for you.
