Correlation of Mitral Annular Plane Systolic Excursion (MAPSE) and Tissue Doppler peak Systolic Velocity with Left Ventricular Systolic Function

The assessment of left ventricular systolic function is the most common indication for performing an echocardiogram, however, no perfect measure of systolic function exists and there are limitations to currently available methods [1]. The most widely used measurement of left ventricular systolic function is the ejection fraction, which also provides important prognostic information [2]. However, its accuracy is limited especially in patients with poor image quality when the endocardial border is not clear enough for tracing where the prevalence of poor image quality was 23-31% in most studies [3]. Moreover major interand intra-observer variability exists [4].
