Apical four-chamber and two-chamber views and three cross-sectional views at different levels of the left ventricle together with a left ventricular three-dimensional cast at baseline (a), low dose (b), high dose (c), and recovery (d) phases of the dipyridamole echo test are shown

Two points of the LV endocardium at the edges of the mitral valve and one at the LV apex were marked manually in the AP2CH and AP4CH views. Then, the 3D-endocardial surface was automatically reconstructed and tracked in 3D space throughout the cardiac cycle [Figure 1].
Apical, midventricular, and basal left ventricular rotation-time curves together with left ventricular volume change-time curve are presented during dipyridamole stress-induced vasodilation. Baseline, low dose, high dose, and recovery data of the dipyridamole echo test are shown

Apical, midventricular, and basal LV rotations at each phase of the stress were calculated [Figure 2] together with global unidirectional radial, longitudinal, and circumferential and complex area and 3D strains [Table 1].
