Efficiency of quantitative longitudinal peak systolic strain values using automated function imaging on transthoracic echocardiogram for evaluating left ventricular wall motion: New diagnostic criteria and agreement with naked eye evaluation by experienced cardiologist

Contrast-enhanced echocardiographic measurement of longitudinal strain: accuracy and its relationship with image quality

“…Global longitudinal strain (GLS) measured using speckle-tracking echocardiography (STE) has been shown to be a strong predictor of morbidity and mortality in patients with heart failure, independent of left ventricular (LV) ejection fraction (EF) [1][2][3][4][5][6][7]. It has thus been incorporated into routine clinical practice and has been endorsed by the ASE and EACVI in the recent chamber quantification guidelines [8,9].…”

Reproducibility and experience dependence of echocardiographic indices of left ventricular function: Side‐by‐side comparison of global longitudinal strain and ejection fraction

“…Previous studies have demonstrated that left ventricular (LV) ejection fraction (EF) is a clinically important parameter, which is routinely used to guide patient management in different conditions and highly correlates with prognosis . In the past decade, global longitudinal strain (GLS) has been extensively described and has been incorporated into the clinical practice after it was found to accurately reflect LV function and to provide prognostic information . Although the current echocardiographic chamber quantification guidelines recommend the utilization of these two parameters, they are not routinely quantified, especially strain.…”

Longitudinal strain bull’s eye plot patterns in patients with cardiomyopathy and concentric left ventricular hypertrophy

“…Its clinical application has been intensively studied in patients with various cardiovascular disorders over the last decade [ 4 ]. STI-based automated function imaging (AFI) is a user friendly advancement to evaluate left ventricular (LV) systolic function and regional patterns based on regional LV longitudinal strain values [ 5 ]. The result of AFI is usually presented as a bull’s eye plot showing color-coded and numerical values for peak systolic longitudinal strain of all LV segments.…”
