Reoperative CABG was associated with higher operative mortality; leaves open whether risk-adjusted selection improves outcomes in contemporary cohorts.
Does reoperative coronary artery bypass grafting increase operative mortality and morbidity compared to primary bypass grafting in patients requiring myocardial revascularization?
Reoperative coronary artery bypass grafting is effective with good long-term outcomes but carries a significantly higher operative mortality and morbidity compared to primary CABG, particularly in high-risk patients.
