Figure 15

The true fibre angle, α , (the first row) and the helix angle, α ₁ , (the second row) in the canine LV free wall. vThe solid, red lines correspond to the data from our model, and the dots correspond to the Auckland canine anatomy data from [22]. The left graphs show the upper area of the LV (ψ = 30° at the epicardium); the centre graphs, the middle area (ψ = 45°); and the right graphs, the bottom area (ψ = 60°). The abscissa axis reflects the position of a point in the thick layer of the LV wall, 0 corresponds to the endocardium (the trabecular LV zone is not taken into account), 1 corresponds to the epicardium. The colour of the points corresponds to the five different longitudes (ϕ) at the LV free wall.
