Assessment of Mechanical Properties of Common Carotid Artery in Takayasu's Arteritis Using Velocity Vector Imaging

Association of Carotid Arterial Circumferential Strain With Left Ventricular Function and Hemodynamic Compromise During Off-Pump Coronary Artery Bypass Surgery

“…27, 28 The biggest benefit of CCA CirS is that assessment of the carotid artery has a great advantage for determination of vascular stiffening, based on its relative proximity to the heart and close interaction with cardiac performance, greater tendency for atheroma formation, and accessibility for ultrasonography. 12 Moreover, the superiority of CCA CirS, over carotid IMT and conventional measures of local stiffness of the carotid artery including elastic modulus, distensibility coefficient or β stiffness index, as a diagnostic tool, has been reported.…”

Asynchronous arterial systolic expansion as a marker of vascular aging

“…Assessment of arterial mechanics by velocity vector imaging VVI is an ultrasound technique using two-dimensional speckle tracking to assess tissue deformation [8][9][10]. VVI allows the direct assessment of vascular mechanics by measuring arterial tissue strain and strain rate.…”

“…As arterial changes with aging are not uniform throughout the arterial tree, methods capable of detecting local vascular changes would be helpful. Recently, velocity vector imaging (VVI), a novel method based on speckle tracking, has enabled rapid and direct quantitative assessment of tissue strain and strain rate [8][9][10][11]. Here, we investigated whether arterial expansion during systole assessed by VVI differed with aging and whether such measurements would be more helpful in discriminating arterial changes associated with aging.…”

Quantitative Assessment of Aortic Elasticity With Aging Using Velocity-Vector Imaging and Its Histologic Correlation

“…With the availability of more advanced ultrasound techniques, a novel automated speckletracking method using velocity-vector imaging (VVI) software has facilitated the assessment for angle-independent and instantaneous quantification of arterial elastic properties by providing the 2-dimensional-derived tissue radial velocity (RV), circumferential strain, and strain rate in both regional and segmental aspects. [12][13][14][15] We previously showed that arterial assessment using VVI represents a new method for quantifying vascular alteration not only in the clinical conditions of vasculitis 12,13 but also in other disorders associated with aging. 16 Despite these investigations, further histological validation will facilitate the clinical application of VVI.…”
