Comparative outcomes of percutaneous transvenous mitral commissurotomy between low and high Wilkins score.

BACKGROUND:Percutaneous transvenous mitral commissurotomy (PTMC) is one of the non-surgical methods for patients with significant mitral stenosis. It is less invasive, less complicating with better outcomes compared to surgery. The Wilkins score ≤8 is used to select patients for PTMC, but the results of several studies suggest that PTMC can also be successful in a higher Wilkins score. The aim of this study is to compare the outcomes of PTMC between two groups. METHODS:In this retrospective study, patients who underwent PTMC between April 2011 and December 2019 were included. Patients were divided into two groups based on Wilkins score: 196 patients (57.64%) with a Wilkins score ≤8 (group I) and 134 patients (39.4%) with a Wilkins score >8 (group II). RESULTS:There was no difference in demographic characteristics between two groups except for age ( ppCONCLUSION:This study shows that the Wilkins score with a cutoff value of 8 is not suitable for patient selection and novel criteria including both mitral valve features and other variables affecting the PTMC outcomes is needed.
