Re-operative Coronary Artery Bypass Grafting: A Review of Changing Pattern and Outcomes

Abstract

Re-operative coronary artery bypass grafting (CABG) prevalence had markedly changed over the last decades. This change had been also noticed in patients' risk profile and outcomes. The aim of this review is to highlight large multi-and single-center studies investigating the change in pattern, techniques, and outcomes of re-operative CABG globally. It is meant to be a reference that can help cardiac surgeons for a better understanding of our current situation with this challenging operation.

Long-term Outcomes After Reoperative Coronary Artery Bypass Grafting

“…8 Because of progression of the disease, as well as the use of percuntaneous coronary intervention (PCI), contemponary rates of reoperative CABG are approximately 2.2% of all CABG procedures and have been declining. 9,10 Despite the increased use of PCI in place of redo CABG and the improvement in PCI techniques, there remains a distinct group of patients who require reoperative CABG for anatomic reasons. 11,12 Recently, hospital mortality in the redo CABG group was reported to be more than double (2.2% vs 4.7%) that of first-time CABG.…”

“…11,12 Recently, hospital mortality in the redo CABG group was reported to be more than double (2.2% vs 4.7%) that of first-time CABG. 9 However, because of improving outcomes in older adult patients, 11,13 reoperative CABG may be an important and viable option in a select group of patients whose anatomy is not amenable to PCI. Nonetheless, there is a known increased risk of morbidity and mortality in reoperative cardiac surgical patients, and reoperative CABG should be performed only in highly selected patients on the basis of their comorbidities.…”
