Implication
Mitral valve anatomy predicts long-term outcomes after percutaneous mitral commissurotomy; leaves open whether anatomy-based selection improves survival.

Intervention
Percutaneous mitral commissurotomy

Outcome
Event-free survivalcomposite
Mitral valve anatomy and patient age are powerful predictors of long-term event-free survival after percutaneous mitral commissurotomy, suggesting immediate valve replacement may be preferable for older patients with unfavorable anatomy.
