Example of left ventricular longitudinal strain measurements in a patient with repaired aortic coarctation. The LV was traced in the apical four-, two-, and three-chamber views at end-diastole. The walls were automatically divided into seven segments at each view and the global longitudinal strain at each view was calculated (a–c). The segmental strain measurements were plotted in a bull’s eye and the left ventricular global longitudinal strain based on all three apical views was calculated (d).
