Functional assessment of jailed side branches in coronary bifurcation lesions using fractional flow reserve.
OBJECTIVES This study was designed to assess the functional significance of side branches after stent implantation in main vessels using fractional flow reserve (FFR). BACKGROUND Little is known about the functional significance of side branches after stent implantation in main vessels in coronary bifurcation lesions. METHODS Between May 2007 and January 2011, 230 side branches in 230 patie...
متن کاملHemodynamic changes by flow diverters in rabbit aneurysm models: a computational fluid dynamic study based on micro-computed tomography reconstruction.
BACKGROUND AND PURPOSE The effect of flow diverter (FD) on hemodynamic changes observed in aneurysms is inevitably affected by the actual structural configuration of deployed FD. We studied the resultant hemodynamic changes after implantation of FDs using computational fluid dynamic simulations based on micro-computed tomography reconstructions in rabbit aneurysm model. METHODS The FDs by mic...

15 صفحه اولIntra-aneurysmal pressure and flow changes induced by flow diverters: relation to aneurysm size and shape.
BACKGROUND AND PURPOSE Effects of blood flow modification by flow diverters are observed to lead often to aneurysm thrombosis and reverse remodeling. For this process, to further understand the potential roles of intra-aneurysmal blood pressure changes and aneurysm morphologies, 23 patients were studied by numeric simulation. MATERIALS AND METHODS 3D imaging of aneurysms of different sizes an...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
