This population-based cohort study examined midterm outcomes of surgical aortic valve replacement with mechanical or bioprosthetic valves in patients less than 50 years old. A total of 991 patients were included. Multivariable Cox regression showed no significant difference in overall survival, with a median follow up period of 6.2 years. However, reoperation-free survival was significantly decreased and risk of reoperation was increased in those who received bioprosthetic valves. Although a difference in overall survival was not apparent in this study, the lower rate of reoperation with mechanical valves might have an impact on long-term survival.

To show a difference between bio and mech valves you need 20 years of follow up. If your follow up time is less than the expected lifetime of the biological valve then both valves will look as if they perform similarly. This is a lifetime management issue and six years doesnt constitute a lifetime
I think they have to till us about any difference regarding bleeding and thromboembolic events
