Off pump versus on pump coronary artery bypass surgery in Shahid Rajaei Heart Center

Back ground:The recent revival of the coronary artery bypass technique without extracorporeal assistance constitutes one of the major revolutions in the cardiovascular community in the last decade. We don’t have any report about the results of OPCAP and compare it with on pump operations in our center and we decide to compare these two techniques in our center.Methods:In a randomize trial 235 patients selected and divided in two groups. Urgent, emergent and redo operations were not selected. Risk factors were the same in two groups.Results:We operated 128 patients with pump and 117 patients without pump randomly. Risk factors were the same in two groups .mean pump time was 99 minutes and mean clamp time was 47 minutes. needs for blood transfusions,Inotrope usage, and balloon pump usage, needs for reoperation,ICU stay and hospital stay, complications and mortality were the same in two groups but post operational hemorrhage was higher in off pump group.Conclusion:off pump coronary artery bypass is a good alternative in our center and we can use this technique in patients without any hesitancy.
