Objectives: Percutaneous mitral balloon commissurotomy (PMBC) remains the preferred treatment for patients with severe symptomatic rheumatic mitral stenosis (MS) and suitable anatomy. The objective of this study was to propose a new score for the prediction of immediate and late success.

Methods: This is a single-center, retrospective analysis of all 1582 patients with severe mitral stenosis who underwent PMBC from August 1987 to July 2010.
