Abstract: Introduction: Coronary-Artery Bypass Grafting (CABG) is currently a heart bypass surgery procedure that is often performed and with developing technology. The most common CABG techniques are on-pump and off-pump. This difference in surgical technique affects the final postoperative outcome, namely the length of stay and mortality of patients in the cardiac ICU. On- pump CABG performed at cardiopulmonary bypass is one of the most commonly performed procedures and an excellent treatment for ischemic heart disease. However, the results of a recent retrospective study found that length of stay and postoperative mortality can be reduced when coronary artery bypass surgery is performed using the off-pump technique.
