On-pump beating heart coronary revascularization: Is it valid for emergency revascularization?

Area of Science:

• Cardiovascular Surgery
• Cardiac Surgery
• Minimally Invasive Cardiac Surgery

Background:

• On-pump beating heart coronary artery bypass grafting (CABG) is an alternative to conventional on-pump surgery for acute coronary syndrome requiring emergency revascularization.
• This study details clinical experience and early outcomes of on-pump beating heart CABG in acute coronary syndrome patients.

Purpose of the Study:

• To evaluate the clinical experience and early outcomes of on-pump beating heart coronary artery bypass grafting (CABG) in patients with acute coronary syndrome.
• To assess the safety and efficacy of this technique as an emergency revascularization strategy.

Main Methods:

• Retrospective study conducted between August 2009 and October 2015 at a regional training and research hospital in Turkey.
• Included 316 patients who underwent isolated on-pump beating heart CABG without cardioplegic arrest by a single surgeon.
• Compared outcomes against conventional CABG procedures.

Main Results:

• The average time from acute myocardial infarction onset to CABG was 10 hours.
• Hospital mortality was 2.9% (9 patients); 12 patients experienced low cardiac output syndromes, with 8 developing renal dysfunction (none requiring hemodialysis).
• Mean intensive care unit stay was 3 days, and mean hospital length of stay was 7 days.

Conclusions:

• On-pump beating heart revascularization is a suitable option for emergency CABG in high-risk patients with multivessel coronary artery disease.
• The technique shows promising early outcomes, suggesting its potential as a valuable alternative surgical approach.
