Key result
Bioprosthetic tricuspid valves show no benefit over mechanical valves for long-term mortality or reoperation.
Why the study?
The ideal valve substitute for tricuspid valve replacement in patients with severe isolated tricuspid regurgitation remains unclear.
Does bioprosthetic tricuspid valve replacement improve outcomes compared to mechanical tricuspid valve replacement in patients with severe isolated tricuspid regurgitation?

Does bioprosthetic tricuspid valve replacement improve outcomes compared to mechanical tricuspid valve replacement in patients with severe isolated tricuspid regurgitation?
Absolute Event Rate: 4.7% vs 3%
p-value: p=0.719
In patients with severe isolated tricuspid regurgitation undergoing first-time replacement, there is no significant difference in survival or reoperation rates between bioprosthetic and mechanical valves.
Weitao Liang (2019) conducted a cohort in Severe isolated tricuspid regurgitation (n=76). Bioprosthetic valve vs. Mechanical valve was evaluated on All-cause mortality (p=0.719). Bioprosthetic and mechanical valves showed no significant difference in long-term mortality (4.7% vs 3.0%, p=0.719) or need for reoperation (2.3% vs 3.0%, p=0.849) after first-time tricuspid valve replacement.
