impact of side-branch flow in coronary bifurcation intervention
background: the optimal strategy in percutaneous coronary intervention (pci) for coronary artery bifurcation lesions has yet to be agreed upon. we compared a strategy for stenting the main vessel to provide a complete perfusion flow in the side branch, namely thrombolysis in myocardial infarction (timi) - iii, with a strategy for intervention in both the main vessel and the side branch (mv + sb...

متن کاملCoronary fractional flow reserve measurements of a stenosed side branch: a computational study investigating the influence of the bifurcation angle
BACKGROUND Coronary hemodynamics and physiology specific for bifurcation lesions was not well understood. To investigate the influence of the bifurcation angle on the intracoronary hemodynamics of side branch (SB) lesions computational fluid dynamics simulations were performed. METHODS A parametric model representing a left anterior descending-first diagonal coronary bifurcation lesion was cr...
متن کاملShear Laver Coupling with Side-branch Resonators
High velocity flow past the junction of a side branch with a pipe can result in the excitation of depth-mode standing waves in the branch. The shear layer separating the main stream flow and the cavity provides coupling between the driving and the driven fl ow. Photographi c evi dence i ndi cates that 1arge scale vortex structures develop at the shear layer. The vortex formation process involve...
متن کاملImpact of main branch stenting on endothelial shear stress: role of side branch diameter, angle and lesion.
In-stent restenosis and stent thrombosis remain clinically significant problems for bifurcation lesions. The objective of this study is to determine the haemodynamic effect of the side branch (SB) on main branch (MB) stenting. We hypothesize that the presence of a SB has a negative effect on MB wall shear stress (WSS), wall shear stress gradient (WSSG) and oscillatory shear index (OSI); and tha...
