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

Background

: When acute coronary syndrome patients ne-

cessitate immediate revascularization, heart-on-pump coro-

nary artery bypass grafting may be regarded as a viable

substitute for conventional on-pump surgery. Our clini-

cal experience and initial outcomes of heart-on-pump coro-

nary 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 pa-

tients who had undergone coronary artery surgery. Dur-

ing this period, the same surgical team performed coronary

artery bypass surgery on 411 of these patients, who un-

derwent 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 by-

pass grafting (CABG). A mean of 4.0 grafts was applied

(2.2

±

1.1). Mortality in hospitals was calculated for six-

teen patients. Following surgery, twenty-six patients devel-

oped an inadequate cardiac output syndrome. Despite hav-

ing 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 hos-

pitalization was 9.2 (4.3

±

2.4) days.

Conclusion

: We be-

lieve 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
