Abstract: Coronary artery Bypass surgery is the most widely used and reliable treatment option for highly occluded coronary artery. In this study a computational technique is used to estimate the velocity profile and Wall shear stress distribution in a complete anastomosis model. Coronary artery is supposed to be fully occluded and the blood flow issued from the bypass graft is investigated. An optimized bypass model is proposed for Coronary artery bypass surgery. Complex flow patterns are found near the both proximal and distal part of anastomosis. Low velocity recirculation zone are found both upstream and downstream of the stenosis. Wall shear stress distribution is calculated at the different location of anastomosis, which is the main factor in the bypass graft failure.
