Distribution of the measurements of the mean average clockwise and counter-clockwise RV averaged over one cardiac cycle and peak RV in millilitres and % (based on the flow volumes in the corresponding vessel section) in the ascending aorta, the aortic arch, and the thoracic descending aorta. Comparisons between percentages of clockwise and counterclockwise flow volumes. †, comparison between clockwise and counter-clockwise/patients and volunteers/patients and patients overall. RBV, rotating blood volume; SD, standard deviation; L-R, left coronary-right coronary; L-N, left coronary-non-coronary; R-N, right coronary-non-coronary; RV, rotational volume.
