Correlation between mitral CT calcium score and Wilkin's score in rheumatic mitral stenosis: added value of cardiac CT

Abstract

Abstract Introduction Wilkin's score, as one of the predictors used to determine the transcatheter or surgical approach may be lacking in objectivity because of potential inter-observer variability. Materials and methods A cross-sectional pilot study was done to assess the correlation between Wilkin's score and Wilkin's Calcium score to the result of the Mitral Computed Tomography Calcium Score. Result Mitral computed tomography calcium score has moderate to strong correlation to Wilkin's calcium score (Correlation 0.738 (Strong correlation), p 0.01) and Wilkin's score (Correlation 0.626 (Moderate correlation), p 0.039). Two of the samples showed zero calcium ct score; however, they scored two in Wilkin's calcium score. Meanwhile, mitral computed tomography calcium score has a weak correlation to the mitral valve area (Correlation −0.294 (Weak correlation), p 0.38 – Statistically not significant). Instead, Wilkin's Calcium Score and Wilkins Score have moderate to strong correlation to the mitral valve area (Correlation −0.609 (Moderate correlation), p 0.047; Correlation −0.722 (Strong correlation), p 0.012). Conclusion Mitral CT calcium score may be incorporated or complement the Wilkin's Score to assess the viability of using percutaneous balloon mitral valvuloplasty (PBMV) as the treatment of choice for mitral stenosis. This is a consideration that Mitral CT calcium score is free from inter-observer variability and thus becomes a gold standard to assess calcium content in the mitral valve.
