I am 29. I have had two open heart surgeries, three valve replacements, one valve repair, and an ascending aortic aneurism repaired with a Dacron graft. I can't really explain why, but it's always somewhat comforting to find other people with the rare experience of having dealt with their mortality at a relatively young age. Thank you for sharing this. You are not alone, and your experiences are appreciated.
I also find it comforting to discover other young people who have weird hearts. Even cardiac doctors and nurses remark on my age.
Further, there is a medical unit in London called GUCH (Grown-Up Congenital Heart) that was created specifically for people like us who had heart problems early on in life. The need wasn't there before because, in the past, we'd all be dead by adulthood.
