I made my decision for a tissue valve but not for noise avoidance reasons. In terms of your options with either mechanical or tissue options; I summarized my decision based on the following consideration. The newer the valve, the potentially greater the benefits / performance; however; newer valves will naturally have a shorter track record than the newer valves. Once I made the decision on valve type with lots of input from my cardio and surgeon, I left the decision on specifically which valve to use up to my surgeon.
Good luck and your decision. I agonized over mine for months, but once I made it, it was a major relief... one more unknown out of the way.
