Fig. 3From: Myofiber organization in the failing systemic right ventricleGraphs showing the transmural distributions of helix angle for the MA/AA heart (top), the DIRV heart (second), the C-TGA heart (third) and the hypertrophied but structurally normal RV (RVH ‘normal’) (bottom). Helix angle measurements were made at 5 sites distributed evenly around the free walls of the ventricles along a transmural line normal to a line tangent at the epicardial surface. Data were plotted from epicardial surface (left) to endocardial surface (right) with each line (varying shades of blue) representing one of the 5 positions around the ventricleBack to article page
