Group mean (±SD) data from 9 hearts. ED = reference configuration; ES = deformed configuration.. Eff = Fiber strain; Ess = Sheet strain; Enn = Strain normal to laminae; Efs = Fiber-Sheet shear; Efn = Fiber-Normal shear; Esn = Sheet-Normal shear.
p<0.05 lateral vs. anterior fiber-sheet absolute strain values at the same wall depth; All data between the anterior and lateral LV wall at different levels were compared using repeated-measures ANOVA.
