BACKGROUND: To compare the Wilkins, Padial and Philippine Heart Center (PHC) echocardiographic scoring systems in predicting the outcome of patients with mitral stenosis undergoing percutaneous mitral commissurotomy (PTMC).

METHODS: This is a validation study of the three scoring systems in 60 patients with mitral stenosis admitted for PTMC. Patients were scored prior to PTMC to predict outcome and compared to the actual outcome post-PTMC based on the final mitral valve area of > 1.5cm2 and a change in the valve area of > 25 percent for those with an initial valve area of > 1.5cm2. Statistics used were students t-test, Fischer test, kappa coefficient and odds ratio.

RESULTS: The Wilkins scoring system showed the highest sensitivity (80 percent) and positive predictive capacity (PPV=32.4 percent) based on the cut-off score of 7. It consistently showed the best agreement in identifying risk for suboptimal outcome post-PTMC (k= 0.16 +/- 0.097) and best able to predict outcome (OR=3.2).

CONCLUSION: The Wilkins scoring system can best predict outcome post-PTMC and should remain as the reference standard for evaluating patients who may undergo PTMC. (Author)
