Feasibility, accuracy and prognostic value of fully automated speckle tracking analysis-derived left ventricular ejection fraction and global longitudinal strain.

ABSTRACT: Left ventricular ejection fraction (LVEF) has been widely used for LV systolic assessment. However, it has drawbacks including large observer variability and unsatisfactory detectability of subclinical dysfunction. LV global longitudinal strain (LVGLS) by speckle-tracking on two-dimensional echocardiography (2DE) has been reported to be superior to LVEF. However, it may be influenced by the different methodology (manual versus semi-automated analyses) and biased study cohorts. A fully automated analysis can alleviate drawbacks of the LVEF and allow fair comparison between LVEF and LVGLS. We sought to evaluate the feasibility, accuracy of LVEF, and LVGLS measurements by the novel fully automated 2DE software against manual analysis and cardiac MRI feature-tracking (CMR-FT). Additionally, we
