Coronary artery bypass without extracorporeal circulation pump in acute coronary syndromes: a single-center observational study

In our experience, OPCAB proved to be a feasible option in specialized centers with expertise, characterized by low mortality, minimal need for conversion to CPB, and high success rates in complete revascularization using arterial grafts.Age and baseline ejection fraction significantly influence hospital outcomes, although these results should be correlated with long-term randomized studies.
