Abstract
Eur J Echocardiography Abstracts Supplement, December 2006 leaflet separation index to predict a good valve opening was 0.87. Using a threshold value of 0.98 cm, sensitivity, specificity, positive predicted value and negative predicted value were 85%, 77%, 82% and 80% respectively. Conclusion: In this large study group of patients with a wide range of MS severity, mitral leaflet separation index was well correlated to the planimetry and a threshold value of 0.98 cm could predict a good PMC result with high sensitivity and specificity. Thus this new index, as a semi-quantitative method, seems to be a useful and complimentary method for MS severity assessment in the setting of PMC.
