I had Rheumatic Fever when I was a baby and had heart damage from it. My 1st surgery was more than 50 years ago. My second 19 years ago when I had a Mitral Valve replaced with a man made one. Yes, it clicks, but as long as it is clicking I know I'm okay. 2 years ago I had a pacemaker put in, so now I am really bionic. I am so very grateful for all these wonderful advances that have been made in heart care over the years, if it weren't for these advances I would have died over 50 years ago and left my 3 little kids without a mother.
