Mitral regurgitation after percutaneous valvuloplasty by the INOUE technique for mitral stenosis

ABSTRACT

Background: Mitral Regurgitation (MR) is a severe complication after percutaneous valvulopalsty for Mitral Stenosis (MS). Objective: To study some predictors, mechanisms and outcome of MR immediately and 3 months after percutaneous valvuloplasty (PMV) by the Inoue technique for mitral stenosis.Subjects and method: 43 patients with MS were followed up for 3 months after PMV by the Inoue technique in the Viet Nam National Heart Institute at Bach Mai Hospital between Jan 2007 to Oct 2007. Results: Uneven mitral leaflets and calcium commissures with Padial\u2019s criteria scoring over 10 was a significant predicator of influence of severe MR after PMV.According to Wilkins\u2019 score, only the calcium commissures affected the MR after PMV (p<0.05). Conclusion: Patients with aortic regurgitation and/or mild MR who\u2019s Wilkins\u2019 scores less than 8 and Padial's scores less than 10 had not be influenced by severe MR after PMV.
