hi well nearly 10 month after my op and yea it does cross my mind daily,but normally in a positive way,i had a tissue valve and sometimes my mind wanders to how long it will last? but hey without it my future wouldnt be rosy,the doctors and nurses are brill and hopefully my valve will last 10 to 15 yrs and maybe things will have moved on and i wont need ohs if not well so be it,i class myself as lucky that in this day and age it can be repaired,...........right off to do some xmas shopping lol..................neil
