This review outlines common sources of variability in longitudinal strain measurements and details measures to increase the accuracy and reproducibility of strain parameters.
This review highlights sources of variability in global longitudinal strain measurements and provides strategies to improve accuracy and reproducibility in clinical practice.
Provides practical guidance for standardizing strain measurements; leaves open prospective validation of clinical impact.
Speckle tracking echocardiography offers a unique opportunity to evaluate myocardial function, and global longitudinal strain (GLS) is currently recommended as a measurement of global left ventricular function. To facilitate clinical applicability of the method, collective efforts have been made to standardise strain measurements and to raise awareness of the potential sources of variability. The purpose of this review is to familiarise the reader with the most common sources of variability of longitudinal strain measurements and detail the possible measures to increase the accuracy and reproducibility of strain parameters.
