Myocyte aggregates orientation quantification. For WKY (top) and LAD (bottom) hearts, respectively: Ventricular helical angle maps in (a,e) four chambers view, as well as in (b,f) apical and (c,g) basal cross sections slices (marked with dashed white lines in the four chambers views). Colour coded by helical angle values. (d,h) Transmural profile from left-side endocardium to right-side endocardium of helical angle in the septal wall (dashed triangular area highlighted in c and g) at three different apico-basal positions (marked with dashed white lines and numbers in the four chambers views: 1-apical, 2-equatorial, 3-basal).
