On-pump CABG causes better revascularization compared to off-pump CABG, while off-pump CABG has much lower post-operative morbidity and mortality, especially in high-risk patients.
Does off-pump CABG improve post-operative morbidity and mortality compared to on-pump CABG in patients with coronary artery disease?
Off-pump CABG may offer reduced morbidity and mortality in high-risk and elderly patients, though on-pump CABG provides more complete revascularization, suggesting the choice of technique should be individualized.
There are two basic ways of performing coronary artery bypass graft surgery (CABG): on pump CABG and off pump CABG. Off pump CABG is relatively a newer procedure to on-pump CABG and does not require the use of the cardiopulmonary bypass machine. On pump CABG is the more traditional method of performing bypass surgery. However its resultant inflammatory effects cause renal dysfunction, gastrointestinal distress and cardiac abnormalities which have forced the surgeons to look for alternatives to the procedure. An extensive literature search revealed that on pump CABG causes better revascularization as compared to off pump CABG while off pump CABG has a much lower post operative morbidity and mortality especially in high risk patients. We suggest that the technique used should depend on the ease of the surgeon doing the operation as both the methods seem almost equally efficient according to the review.
Khan et al. (Mon,) conducted a review in Coronary artery disease. Off-pump coronary artery bypass (OFCAB) vs. On-pump coronary artery bypass (ONCAB) was evaluated. On-pump CABG causes better revascularization compared to off-pump CABG, while off-pump CABG has much lower post-operative morbidity and mortality, especially in high-risk patients.
