Off pump Versus On pump Coronary Artery Bypass Grafting: Short-term Outcomes

BACKGROUND: Coronary artery disease (CAD) is a major public health issue and a leading cause of death globally. It is one of the most common indications for surgical intervention. There are a lot of different techniques, including CABG, which consists of two approaches: sternotomy and mini-thoracotomy. Different techniques have been developed to improve surgical outcomes, including the use of machine for extracorporal circulation (on-pump) or without it (off-pump). OBJECTIVE: The objective of this study was to assess whether off-pump CABG offers superior short-term outcomes compared to traditional on-pump CABG in patients undergoing isolated CABG.. METHODS: In period between 2022 – 2023, we performed CABG operation in 80 patients. CABG was performed either on- pump or off-pump. RESULTS: The results have shown advantages and disadvantages of one or another type of CABG. We were comparing the duration of surgical procedure, time on mechanical ventilation, drainage volume, neurological incidents, time to discharge, indication for repeat revascularization and mortality between two groups. CONCLUSION: The choice of surgical technique should be based on individual patient factors, including comorbidities and surgical risks. It is important to say that OPCABG is more challenging than ONCABG, and it is very important that OPCABG is done by skilled, experienced and confident surgeon, which contributes to better outcome and survival.
