Key result
Mitral valve repair significantly reduced the risk of short-term mortality compared to replacement in elderly patients (RR 0.41; 95% CI 0.24-0.71; p=0.005).
Why the study?
Although mitral valve repair has shown excellent outcomes, its merit compared to replacement in the elderly population remains debated.
Does mitral valve repair improve short-term mortality and long-term survival compared to mitral valve replacement in elderly patients (≥75 years old)?
Meta-Analysis
Does mitral valve repair improve short-term mortality and long-term survival compared to mitral valve replacement in elderly patients (≥75 years old)?
Relative Risk: 0.41 (95% CI 0.24–0.71)
p-value: p=.005
In elderly patients (≥75 years old), mitral valve repair is associated with significantly lower short-term mortality and better long-term survival compared to mitral valve replacement.

MV repair may confer lower short-term mortality and better survival in elderly patients; leaves open whether selection bias explains observational benefits.
Tommaso et al. (2021) conducted a meta-analysis in Mitral valve disease. Mitral valve repair vs. Mitral valve replacement was evaluated on Short-term mortality (RR 0.41, 95% CI 0.24-0.71, p=.005). Mitral valve repair significantly reduced the risk of short-term mortality compared to replacement in elderly patients (RR 0.41; 95% CI 0.24-0.71; p=0.005).
