Which diameter and angle rule provides optimal flow patterns in a coronary bifurcation?
The branching angle and diameter ratio in epicardial coronary artery bifurcations are two important determinants of atherogenesis. Murray's cubed diameter law and bifurcation angle have been assumed to yield optimal flows through a bifurcation. In contrast, we have recently shown a 7/3 diameter law (HK diameter model), based on minimum energy hypothesis in an entire tree structure. Here, we der...
متن کاملimpact 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 Artery Bifurcation Lesions; A Review and a Guide for Specific Interventional Techniques
Percutaneous coronary intervention in the setting of coronary bifurcation lesions is associated with increased risk for complications. The goal of this manuscript is to review the currently available classifications for coronary artery bifurcation lesions with a guide to the use of specific coronary bifurcation techniques based on lesion characteristics
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...
