Its application among low ejection fraction patients is limited. The aim of our study is to evaluate this technique among patients with low ejection fraction and to compare results with off-pump bypass technique. Methods This retrospective study includes 137 patients with ejection fraction below 0.35 who underwent isolated coronary artery bypass surgery. 39 patients underwent myocardial revascularization using on-pump beating heart ONCAB BH while 98 patients had off-pump beating heart OPCAB . Different preoperative operative and postoperative variables were evaluated among both groups. Results Patients profiles and risk factors were similar among both groups except for the number of patients undergoing redo CABG which was significantly higher among ONCAB BH 13 vs 3 p 0.025 . Ejection fraction EF varied from 10-34 . The mean EF for patients who underwent ONCAB BH was 28 6 in comparison to 26 5 for OPCAB patients P 0.093 . Predicted risk for surgery according to EuroSCORE was similar among both groups P 0.443 . The number of grafts performed per patient was significantly more among patients who underwent ONCAB BH 2.2 0.7 Vs 1.7 0.7 P 0.002 . Completeness of revascularization was significantly greater in the ONCAB BH patients 72 Vs 46 P 0.015 . The incidence of hospital mortality and combined major morbidity was more among ONCAB BH in comparison to OPCAB but the difference was not significant. However the incidence of blood loss ventricular arrythmias inotropic support ICU .
