Key result
Early surgical intervention significantly reduced long-term mortality compared with watchful waiting in asymptomatic patients with severe mitral regurgitation (HR 0.38; 95% CI 0.21-0.71).
Why the study?
Does early surgical intervention reduce all-cause mortality at 10 years in asymptomatic patients with severe degenerative mitral regurgitation compared to watchful waiting?
Population

Supports early surgery in asymptomatic severe MR; confirms long-term survival benefit in Level 1 meta-analysis.
Meta-Analysis
Does early surgical intervention reduce all-cause mortality at 10 years in asymptomatic patients with severe degenerative mitral regurgitation compared to watchful waiting?
Hazard Ratio: 0.38 (95% CI 0.21–0.71)
Early surgical intervention in asymptomatic severe degenerative mitral regurgitation may improve long-term survival and increase the likelihood of successful valve repair compared to watchful waiting.
Goldstone et al. (2015) conducted a meta-analysis in Asymptomatic severe mitral regurgitation. Early surgical intervention vs. Watchful waiting was evaluated on All-cause mortality at 10 years (HR 0.38, 95% CI 0.21-0.71). Early surgical intervention significantly reduced long-term mortality compared with watchful waiting in asymptomatic patients with severe mitral regurgitation (HR 0.38; 95% CI 0.21-0.71).
