Abstract : Background Aortic dissection is rare but a potentially life-threatening illness. Apart from hypertension and aortic dilation [1], the aortic root (AR) motion has also been proposed to be another factor leading to dissection [2, 3]. During the cardiac cycle, the aortic annulus is towed due to ventricular traction in systole and is relaxed in diastole. The traction force induces a spatial movement of the aortic annulus and is transmitted to the ascending
