In this review we aimed to present the effects of clamp and shunt usage on vascular endothelium in coronary artery surgery under the light of current literature data.Each surgical team or even each surgeon uses different methods in order to create bloodless surgical site during beating heart surgical procedures.Every method has its own advantages and disadvantages.There is no formed consensus regarding this issue. Surgeons still want to operate on bloodless surgical fields. But, they have concerns about continuity of blood flow and vascular endothelial injury during off-pump coronary surgery. In order to achieve a consensus statement about this issue, multicentric larger studies are needed.
