Clinical Applications of Left Ventricular Global Longitudinal Strain by 2D-Speckle Tracking Echocardiography

Abstract

Evaluation of myocardial strain may be able to circumvent several of the LVEF measurement drawbacks when evaluating LV systolic performance. Regardless of the ultrasound beam's angle of insonation, speckle tracking echocardiography enables the measurement of myocardial strain in three different spatial directions: longitudinal, radial, and circumferential. In clinical practise, longitudinal strain is most likely the strain type most often utilised to describe LV systolic function and has significant prognostic and diagnostic roles in evaluating different myocardial diseases.
