Results of helical and intrusion angles as a function of myocardial depth in percent. 0% is the sub-endocardium, 100% is the sub-epicardium. In the interventricular septum 100% is the right ventricular sub-endocardium. Results are shown as medians with interquartile range. Asterisk indicates statistical significance in individual areas in post-hoc testing using Mann-Whitney U-test
