Key result
Long-term relative survival after heart valve replacement was 83.5% for the total cohort, indicating a smaller mortality gap compared to the general population than standard actuarial survival (75.1%).

Relative survival narrows the mortality gap after valve replacement versus actuarial estimates; supports refined prognostic models in observational cohorts.
Cohort (n=841)
What is the long-term relative survival of patients undergoing heart valve replacement compared to the general population?
Calculating relative survival rather than actuarial survival demonstrates that the difference in survival between heart valve replacement patients and the general population is smaller than previously estimated.
Abdelnoor et al. (1990) conducted a cohort in Heart valve replacement (n=841). Heart valve replacement vs. General population was evaluated on Long-term relative survival. Long-term relative survival after heart valve replacement was 83.5% for the total cohort, indicating a smaller mortality gap compared to the general population than standard actuarial survival (75.1%).
