This paper outlines the methodology and statistical challenges in assessing the long-term performance of artificial heart valves using a large UK multicenter registry.
Drury et al. (1987) conducted an observational in Heart valve substitutes (n=9,859). Artificial valve implants was evaluated on Failure rates of valve implants. Artificial valve implants (N=9,859) from the UK Multicentre Valve Trial were analyzed to assess long-term performance and failure rates, accounting for variability across 22 participating centers.
