The Off Pump Coronary Bypass (OPCAB) team of the Katholieke Universiteit of Leuven presents a debriefing exercise of your OPCAB procedures versus their standard operating procedures. The exercise is divided into two intervals. The first is the "conditioning interval." It prepares the patient for the impact of manipulation and possibility of ischaemia during graft construction. The second is the "anastomotic interval," which begins at the time of the first anastomosis and finishes at the completion of the last.
