Predictors of successful percutaneous transvenous mitral commissurotomy using the Bonhoeffer Multi-Track system in patients with moderate to severe mitral stenosis: Can we see beyond the Wilkins score?

Abstract

The Wilkins valve score is the main topic of this study (1, 3). It is well known that an increase in the valve score leads to reduced MBV success. However, the report solely indicated that the valve score was <8 in both groups. Emphasizing the numerical values of the valve score in the successful and failed valvuloplasty cases and if present, mentioning the difference between them would be more illuminative. We believe that a valve score of <8 in both groups does not mean that the two groups will have similar success rates. The success rate will quite likely decrease with the increasing valve score
