Just thought I would drop this in here as I was perusing it today - Section 11.1.2 has guidance from ACC/AHA for choosing between a mechanical valve and a bio valve as well as Ross autograft. It includes data on longevity of bio valves based on age and valve (aortic and mitral recommendations are different). Has a nice flow chart and other info.

Couple of summary points:
For AVR: under 50 lean mechanical, over 65 lean bio, middle range of 50-65 is debatable
For MVR: under 65 lean mechanical, over 65 lean bio
Ross: narrow band of people under age 50 (usually much younger) who are contraindicated for anticoagulation or are vehemently opposed to it and have access to a comprehensive valve center
There's additional data in there about risks of re-operation and average durability of bio valves for different age groups in there and it talks about other factors like patient compliance with anti-coagulation as well. Factors to consider and underlying research for those in the middle range of age.
Just helpful overview from the medical guidelines for people.
