Illustration of the assessed strain parameters in long and short axis views. Long axis views (left: 4-chamber view) were used for the measurement of global longitudinal strain (GLS), three short axis views at apical, midventricular and basal level (right: apical short axis view) were used to evaluate global circumferential strain (GCS), global radial strain (GRS) and left ventricular (LV) torsion
