yotphix,
It's very good to hear that your heart has gone back to normal. I'm hoping the same happens to me and that I can get back to rigorous cycling, swimming, running and hiking. Thanks for the post. What type and make is your valve?
Carbomedics 29mm. Sorry, can't think what the model name is just now, but it isn't the supra anular Top hat. Just the regular old style in the anulus.
