Phasic blood flow dynamics and wall shear stress (WSS) have the potential to directly modulate endothelial responses, playing an important role in the development of bypass graft occlusion. This study compares phasic blood flow velocity patterns and WSS of the left internal thoracic artery (LITA) used as a composite Y-graft (27 patients, Y-group) and as a single graft (24 patients, S-group) on the left anterior descending (LAD) coronary artery.
