Abstract: Objective To evaluate the aortic wall elasticity using the maximal rate of systolic distension (MRSD) and maximal rate of diastolic recoil (MRDR) and their correlation with the aortic size index (ASI). Methods Forty-eight patients with thoracic aortic aneurysm were enrolled in this study. A standard magnetic resonance imaging (MRI) protocol was used to calculate MRSD and MRDR. Both MRSD and MRDR were expressed as percentile of maximal area/10 -3 … Show more

“…Further studies are required for investigation of the impact of helical flow on WSS and the association between its severity and the development of aortopathy. Novel parameters may contribute to predict the outcome or even improve risk stratification: von Spiczak et al described a quantitative analysis of vortical blood flow for visualization of pathological flow alterations ( 51 ), while Tiwari et al successfully introduced so-called MRSD (maximal rate of systolic distension) and MRDR (maximal rate of diastolic recoil) for evaluation of biomechanical properties of the aorta ( 52 ). Future longitudinal studies should consider these parameters.…”

“…The aortic size index also correlates with maximal rates of systolic distension and diastolic recoil, which may be markers of the aortic stiffness increasing. An analysis of the relationship between the aortic size index, the maximal rate of systolic distension, and the maximal rate of diastolic recoil characterizing the severity of the disease allowed the authors to compensate for having a small study population and no healthy, matched control group [ 13 ].…”
