Hey Dylan
thanks, I am "keeping well" ... spent yesterday doing some bathroom renovations , laying some wall sheets over the studs before I can waterproof and tile.
When it came time for my 3rd op the surgeon (who interestingly was part of the same team who had done my first two ops') laid the facts on the table and said that this operation will not be easy due to the amount of scar tissue. He offered me the choice of valves and said that due to me being healthy and active (hike, cross country ski with my wife, cycle ...) that the chances were that I would not get a long span from a tissue prosthesis. The valve would start to calcify and slow me down and impede my health. Then I would be up for a reop in under 15 years. He made it clear that scar tissue will be even more built up (increases with each operation) and that the operation would then carry even more significant risks. His words were "you will not have surgeons queueing up to do that surgery".
Not knowing anything much about anticoagulation therapy at the time (unlike now) I weighed that carefully and it became obvious quite soon that I would be a fool to do anything else except have a mechanical.
Being an alert and focused professional in I was totally confident that I could manage my INR myself and get the best possible outcome.
I now see that the choice between bio and mech has that fundamental difference. With a mech it will last longer than me, and my health is more or less in my hands. With a bio the process is partly down to chance (do you calcify the valve faster or not) and a totally clear max use by date.
I did not want to put my wife through another surgery nor did I want to take the quite significant risk that I would be injured in the later 4th surgery and be debilitated and a handicap to my wife.
I have written much here on these points and on the potential traps which can befall you on reoperation. I was lucky with my first two, my third gave me a legacy which may increase the risk of a 4th surgery to being nearly certainly deadly.
People make the mistake of treating surgery as a long day of hard work with some pain to workthrough the following day. Its much more than that and the risks are often poorly understood by most.
I write on my blog about these things, hopefully you will find something useful in these posts:

as I say in one of my blog posts:
My wife was distraught at the thought of my surgery (more so than me), she was beside me every step of the way. She said to me in recovery that some of the happiest moments of her life were in seeing me get better every day.
She put on a brave face, but the fact is that she was scared shitless that I would die and she would be left without me.
She was so pleased because she was so relieved. I would not want to put her through that again. If you are a reasonably healthy adult, and you choose a tissue valve you will for sure be putting your loved ones through it again.
Is that something you want to do to them?
