Key result
Percutaneous mitral balloon valvotomy resulted in comparable mortality (RR 0.97) and complications compared to surgical mitral commissurotomy, but significantly increased the risk of new-onset mitral regurgitation and late re-intervention.
Why the study?
Does percutaneous mitral balloon valvotomy improve clinical outcomes compared to surgical mitral commissurotomy in patients with pure mitral stenosis?
Meta-Analysis (n=2,029)
Does percutaneous mitral balloon valvotomy improve clinical outcomes compared to surgical mitral commissurotomy in patients with pure mitral stenosis?
Relative Risk: 0.97 (95% CI 0.45–2.09)
Absolute Event Rate: 4.13% vs 3.24%
Percutaneous mitral balloon valvotomy and surgical commissurotomy have comparable mortality and complication rates, but balloon valvotomy is associated with higher rates of new-onset mitral regurgitation and re-intervention.

PMBV matches surgery on mortality and complications but raises MR and re-intervention risks; supports durability-focused procedure selection in mitral stenosis.
Zhao et al. (2011) conducted a meta-analysis in Mitral stenosis (n=2,029). Percutaneous mitral balloon valvotomy vs. Surgical mitral commissurotomy was evaluated on Mortality (RR 0.97, 95% CI 0.45-2.09). Percutaneous mitral balloon valvotomy resulted in comparable mortality (RR 0.97) and complications compared to surgical mitral commissurotomy, but significantly increased the risk of new-onset mitral regurgitation and late re-intervention.
