It is widely accepted that the use of cardiopulmonary bypass for cardiac surgery is associated with significant morbidity, in particular that secondary to activation of the inflammatory and coagulation systems. It is therefore surprising that almost a decade after the establishment of equipment and surgical techniques enabling coronary artery surgery to be routinely performed without cardiopulmonary bypass, evidence to demonstrate its superiority in all but high-risk patient populations remains controversial. This may, in part, be because the techniques involved are technically demanding with a substantial learning curve. In addition, it is likely that the physiological and pathological processes occurring during coronary artery surgery, whether with cardiopulmonary bypass or without, are more complex than has been previously thought. Many of the trials published relating to off-pump cardiac surgery (OPCAB) are case series, often compared with historical controls, and are
