Answers are grounded in this paper and cite their sources.
MAPSE and tissue Doppler peak systolic velocity are longitudinal function measurements that may serve as alternatives to ejection fraction for estimating LV systolic function, particularly when image quality is poor.
Background: Estimation of left ventricular function has major diagnostic and prognostic importance in cardiac patients. The most commonly used measure of the systolic function of the left ventricle is ejection fraction (EF), however, the accuracy is limited especially in patients with poor image quality. Mitral annular plane systolic excursion (MAPSE) and tissue Doppler peak systolic velocity (TD PSV) are measurements of longitudinal function which has been shown to correlate with LV global systolic function.

A 2017 study conducted a cross-sectional in Left ventricular systolic dysfunction (n=200). Mitral annular plane systolic excursion (MAPSE) and Tissue Doppler peak systolic velocity (TD PSV) vs. Biplane Simpson's method (LVEF) was evaluated on Detection of impaired left ventricular ejection fraction (<50%). Combining mitral annular plane systolic excursion (MAPSE) and tissue Doppler peak systolic velocity (TD PSV) at the medial mitral annulus detected left ventricular ejection fraction <50% with 95.9% sensitivity and 100% specificity.
