Key result
Mitral valve plasty was associated with significantly lower early mortality (OR 0.45) and improved long-term survival (HR 0.61) compared to mitral valve replacement in patients with infectious endocarditis.
Why the study?
While mitral valve plasty shows better clinical outcomes than replacement in degenerative disease, its advantages in patients with infectious endocarditis remain unclear.

Supports preferring mitral valve plasty in infectious endocarditis when feasible; extends observational data but leaves randomized confirmation open.
Meta-Analysis (n=25,615)
Does surgical mitral valve plasty improve clinical outcomes compared to mitral valve replacement in patients with infectious endocarditis?
Odds Ratio: 0.45 (95% CI 0.33–0.61)
In patients with infectious endocarditis, mitral valve plasty is associated with lower early and long-term mortality compared to mitral valve replacement, though it may carry a higher risk of reoperation.
Wang et al. (2023) conducted a meta-analysis in infectious endocarditis (n=25,615). Mitral valve plasty vs. Mitral valve replacement was evaluated on Early mortality (OR 0.45, 95% CI 0.33-0.61). Mitral valve plasty was associated with significantly lower early mortality (OR 0.45) and improved long-term survival (HR 0.61) compared to mitral valve replacement in patients with infectious endocarditis.
