The top row illustrates rest strain imaging in a patient with three-vessel disease, A: Apical 4-chamber (4-CH), B: Apical 2-CH, C: Apical 3-CH view and D: Bull’s eye strain map of left ventricular segments shows mild segmental strain reduction at rest; however, the averaged 4-CH, 2CH, 3-CH and averaged global longitudinal strain was normal

The bottom row illustrates peak stress strain in the same patient, E: Apical 4-chamber (4-CH), F: Apical 2-CH, G: Apical 3-CH view and H: Bull’s eye strain map of left ventricular segments shows severe reduction of the segmental and averaged strain reduction
