Key result
Mitral valve replacement was associated with greater 10-year mortality compared to repair (HR 1.26; 95% CI 1.14-1.39; P<0.0001), driven by higher risk in the first 2 years.
Why the study?
The ideal surgical intervention for secondary mitral regurgitation remains debated.
Does mitral valve repair reduce long-term mortality compared to mitral valve replacement in adult patients with secondary mitral regurgitation?
Meta-Analysis (n=6,566)
Does mitral valve repair reduce long-term mortality compared to mitral valve replacement in adult patients with secondary mitral regurgitation?
Hazard Ratio: 1.26 (95% CI 1.14–1.39)
p-value: p=<0.0001
Mitral valve replacement for secondary mitral regurgitation is associated with higher mortality in the first 2 years compared to repair, but long-term mortality rates become comparable thereafter.
No takes yet. Share an insight, caveat, or question.
May favor repair over replacement to reduce early mortality in secondary MR; extends meta-analytic evidence on time-dependent risks.
Formica et al. (2024) conducted a meta-analysis in Secondary mitral valve regurgitation (SMR) (n=6,566). Mitral valve replacement (MVR) vs. Mitral valve repair (MVr) was evaluated on Long-term mortality for any cause (HR 1.26, 95% CI 1.14-1.39, p=<0.0001). Mitral valve replacement was associated with greater 10-year mortality compared to repair (HR 1.26; 95% CI 1.14-1.39; P<0.0001), driven by higher risk in the first 2 years.
