Today is the first year anniversary of my merchanical valve and also my second year anniversary of my Dacron graft replacement due to a failed repair . I would just like to say a big thankyou to this website and its active members.Without all of you sharing your experiences and knowledge I would not be where I am today.Even though I haven’t posted much I have been on this forum everyday reading posts and my confidence has grown everyday purely on all of your inputs. Knowing that there is so many of you out there going strong has done my confidence the world off good.Best wishes to you all Paul 1972
