Background: There is an increase in the number of patients with severely impaired left ventricle function who referred for CABG. Many studies showed that surgical intervention for those high-risk patients has high survival and wonderful outcome compared to medical treatment.
Aim of work: This study aimed to evaluate our experience with coronary artery bypass surgery in patients with EF [ 25% up to 40%] either to perform surgery using off or on-pump technique and try to conclude which technique may be safer regarding cardiac function.
Patients and Methods: This prospective observational patient cohort study from August 2017 to July 2019 enclosed forty consecutive patients divided into 2 teams every 20 patients either off or on pump technique according to surgeons' expertise. Pre-, intra- and post-operative data were collected for all patients. All survivors were subjected to a 6-months follow-up clinically and by Echocardiograghy assessment.
Results: Improvement of ejection fraction [EF] was encountered in our study; the mean 6-months operative EF improved for each team by [36% versus 37%] for off-pump and on-pump interventions, respectively. There was no statistically important difference in the information collected for each technique [p-value>0.05] regarding most points of comparison.
Conclusion: Results of CABG in high-risk patients were acceptable with on-pump and off-pump techniques with nearly comparable results in our study, at least in the early 6-months after intervention. Intra-aortic balloon usage is valuable when indicated.
