Three-dimensional (3D) speckle-tracking with TomTec 4D Echo Software (TomTec Imaging Systems, Image Arena, Unterschleissheim, Germany). Standard three apical views and one short-axis view of the left ventricle (LV) were automatically extracted from the 3D full-volume data sets. The 3D endocardial surface was automatically reconstructed at LV end-diastole (LVED) (a) and LV end-systole (LVSD) (b). The software provided global longitudinal strain (GLS) (c), global radial strain (GRS) (d), global circumferential strain (GCS) (e), and global principal tangential strain (GPTS) (f) time curves in 16 segments as well as peak global strain and averaged peak strain at three LV levels (basal, mid, and apical)
