Wall shear stress within coronary stents.

In silico models were created from reconstructed μCT scans of coronary stent casts and used for CFD analysis to plot wall shear stress along the vessel. A: Coroflex Blue stent, showing elevated shear stress on the luminal surface of prolapsed struts; B: Matrix stent, showing reduced shear stress downstream of struts; C: Pro Kinetic Energy stent, showing reduced shear stress downstream of struts; D: XTRM-Track stent, showing reduced shear stress downstream of struts and within areas of complex geometry. Flow from left to right, 1 Pa average wall shear stress. Note: the maximum value of the scale bar is set to 3 Pa to better illustrate regions of low flow.
