Figure 6 | Speckle tracking echocardiography to assess left ventricular (LV) mechanics in severe aortic stenosis. a | A patient with severe calcific aortic stenosis and impaired LV longitudinal strain (average global longitudinal strain −11.4%) despite preserved LV ejection fraction. b | Time–longitudinal strain curves for (clockwise from top left) three-chamber, four-chamber, and two-chamber LV apical views, and the polar map with the regional and global values of longitudinal strain. Note that the regions with most impaired longitudinal strain include the basal septum where LV hypertrophy is more pronounced.
