Abstract

Background: while cardiopulmonary bypass (CPB) has mainly been used to conduct the procedure of coronary artery bypass grafting (CABG) (On-pump CABG), CABG without cardiopulmonary bypass (off-pump CABG) may help limiting a number of known heart-lung machine's complications. Objective: to compare short term outcomes of both procedures (off-pump versus on-pump coronary artery bypass graft) in terms of efficiency and safety. Patients and Methods: this prospective randomized study was dedicated to assess the implementation of cardiopulmonary bypass in the cardiothoracic departments of both El Hussein and MKH Hospitals from August 2017 to July 2019. Results: regarding intraoperative data, operation time and the need for cardiac inotropes were significantly high in on-pump group. On the other hand, the total number of grafts utilized in on-pump group was 185 grafts while in off-pump group it was 177 grafts indicating no significant difference in terms of myocardial revascularization. Regarding postoperative data, the postoperative elevation of cardiac enzymes was significantly higher in on-pump group while ventilation time and duration of ICU stay were significantly less in time in off-pump group. Conclusion: off-pump CABG was easy to use and helped lowering the incidence of postoperative complication related to cardiopulmonary bypass with a decrease in both hospital stay and morbidity; there was no difference in post six months’ follow-up, however, excellent results can be obtained with both techniques when done by expert hands.
