Figure 6: Analyses of regional LV function 4 weeks after surgery. Significant wall thinning occurs at ED in anterolateral regions while the posterior region demonstrates significant wall thickening (a). At ES, significant wall thinning is observed in anterior and lateral regions, while a modest decrease is evident in the posterior region (b). While all four regions show reduction in systolic wall thickening, it is only significant in the lateral and posterior regions (c). † versus week 4 sham.
