Abstract

Background: Despite standardization efforts, vendors still use information from different myocardial layers to calculate global longitudinal strain ( GLS). Little is known about potential advantages or disadvantages of using these different layers in clinical practice. The authors therefore investigated the reproducibility and accuracy of GLS measurements from different myocardial layers.
