**3. Coronary endarterectomy**

Coronary endarterectomy is performed when the target has severe atherosclerosis and is not a suitable target. This procedure removes the atherosclerotic plaques with the intima and allows the conduit be anastomosed to the target. Often, decision of coronary endarterectomy is made intraoperatively and conduit is anastomosed to the endarterectomized vessel. This requires precise technique and experience since inadequate procedure leads to occlusion of the native artery and the bypass conduit. Main perioperative challenge is maintainance of patency because removal of the endothelial surface of the coronary artery disposed to platelet aggregation and subsequent thrombus formation. Therefore, anticoagulation method includ‐ ing usage of postoperative heparin and clopidogrel is encouraged.
