Abstract: Background: Assessing left ventricular function is a most common indication for echocardiogram. Mitral annular plane systolic excursion (MAPSE) has been used as a substitute measure for left ventricular function. The aim of this study was to evaluate the accuracy of MAPSE for predicting left ventricular function (Ejection fraction) on the basis of a echocardiogram. Methods: The study was designed as a prospective analysis of 250 patients echocardiographic studies performed in a institute. MAPSE measurement was performed and compared with the EF as determined by an echocardiographer. Results: Using the 250 studies, an algorithm was developed to conclude EF. Cutoff value for normal EF (?13 mm for men and ?11 mm for women) and decreased EF (For the mid-range MAPSE values. By comparing the predicted EF and the expert-reported EF, positive and negative predictive values, sensitivity (73%?92%), specificity (81%?100%), and accuracy (82%?86%) of MAPSE for predicting EF were calculated. Conclusions: measurement of MAPSE by an observer was found to be a most accurate predictor of EF.
