Experimental study of laminar blood flow through an artery treated by a stent implantation: characterisation of intra-stent wall shear stress

Edge Vascular Response After Resorption of the Everolimus-Eluting Bioresorbable Vascular Scaffold – A 5-Year Serial Optical Coherence Tomography Study –

“…30,31 Moreover, exposing the endothelial cells to a homogeneous shear stress can potentially prevent neointimal growth and neoatherosclerosis in the late phase in all regions (scaffold, transitional region, and edge segment). [32][33][34][35] According to the results from the late phase (between 2-3 and 5 years), the favorable lumen evolution of the scaffold itself apparently abrogated the EVR phenomenon. At the present time there is no comparable late observation of metallic DES.…”

An Atherosclerotic Coronary Artery Phantom for Particle Image Velocimetry

“…), filled and perfused with the described glycerol mixture, and the bath pressure was adjusted by means of controlled air pressure connected to the observation receptacle. The phantom was also perfused with the same glycerol mixture than the immersion bath, but some particles of titanium (TiO 2) , having a near size of 5 µm, were included in order to reflect some laser light for displacement tracking purposes. The phantom, enclosure, bath and flow were all transparent, therefore allowing appropriate optical conditions for PIV acquisition.…”

Pulsatile Flow in Coronary Bifurcations for Different Stenting Techniques

“…The appearance and progression of the atherosclerotic disease depend on individual characteristics, determined genetically, on the presence of risk factors and on local factors related to the vascular anatomy and hemodynamic variables. The consequences of local variations in the flow have been studied in different experimental models (Benard et al, 2003). Most of them suggest a correlation between low endothelial shear stress and wall thickness, although there is discrepancy in the results (Zarins et al, 1983;Gnasso et al, 1997 andShaaban et al, 2000).…”
