Key result
Bioprosthetic valves offer no survival benefit over mechanical valves in ESRD but reduce complications.
Why the study?
There is little evidence guiding heart valve prosthesis selection in patients with end-stage renal disease on dialysis.
Does bioprosthetic valve replacement improve survival or reduce valve-related complications compared to mechanical prostheses in patients with ESRD on dialysis?
Population
6350 patients with ESRD on dialysis undergoing valve replacement
Comparison
Bioprostheses versus mechanical prostheses
Design
Systematic review and meta-analysis of 12 studies

No survival difference between prostheses; leaves open optimal valve choice pending higher-quality evidence in dialysis patients.
Meta-Analysis (n=6,350)
Does bioprosthetic valve replacement improve survival or reduce valve-related complications compared to mechanical prostheses in patients with ESRD on dialysis?
Hazard Ratio: 1.3 (95% CI 1–1.9)
p-value: p=0.09
In patients with ESRD on dialysis, bioprosthetic heart valves offer similar survival to mechanical valves but with significantly fewer valve-related complications.
Chan et al. (2011) conducted a meta-analysis in End-stage renal disease (ESRD) on dialysis (n=6,350). Bioprostheses vs. Mechanical prostheses was evaluated on Survival (HR 1.3, 95% CI 1.0-1.9, p=0.09). Bioprosthetic valve replacement showed no survival difference compared to mechanical prostheses in patients with ESRD on dialysis (HR 1.3; 95% CI 1.0-1.9; p=0.09), but had fewer complications.
