On Pump Beating Heart Coronary Artery Surgery in Patients Requiring Urgent Revascularization.

Abstract

Background: When acute coronary syndrome patients necessitate immediate revascularization, heart-on-pump coronary artery bypass grafting may be regarded as a viable substitute for conventional on-pump surgery. Our clinical experience and initial outcomes of heart-on-pump coronary surgery in patients with acute coronary syndrome are detailed in this article.

Method: This research endeavor was a retrospective analysis that spanned the years March 2011 to August 2023. The sample size comprised 2816 patients who had undergone coronary artery surgery. During this period, the same surgical team performed coronary artery bypass surgery on 411 of these patients, who underwent beating heart surgery while on cardiopulmonary bypass support and without cardioplegic arrest; this was done under emergency conditions.

Result: 9.3 ± 2.2 hours elapsed between the initiation of acute myocardial infarction and the commencement of coronary artery bypass grafting (CABG). A mean of 4.0 grafts was applied (2.2 ± 1.1). Mortality in hospitals was calculated for sixteen patients. Following surgery, twenty-six patients developed an inadequate cardiac output syndrome. Despite having renal dysfunction, none of the eight individuals needed hemodialysis. The mean duration of stay in intensive care was 3.2 (2.2 ± 1.1) days, while the mean length of hospitalization was 9.2 (4.3 ± 2.4) days.

Conclusion: We believe that for high-risk patients with multivascular coronary artery disease who require an emergency coronary artery bypass graft, on-pump beating heart revascularization could be a viable option.
