Key result
Narrow bifurcation angles and severe stenosis predict higher side branch occlusion risk via disturbed flow.
Why the study?
Main branch stenting carries a significant risk of side branch occlusion, a complication with irreversible clinical consequences.

Bayatian et al. (2025) studied Coronary bifurcation atherosclerosis. Main branch stenting (computational modeling) was evaluated on Side branch occlusion risk and hemodynamic parameters (disturbed flow, oscillatory shear index, wall shear stress). Computational modeling revealed that narrow bifurcation angle and higher main branch stenosis severity promote disturbed flow and structural deformation, increasing the risk of side branch occlusion.
