Beating-Heart Versus Conventional On-Pump Coronary Artery Bypass Grafting: A Meta-Analysis of Clinical Outcomes

BH-ONCAB is a safe and comparable alternative to C-ONCAB in terms of early mortality and late survival. Furthermore, BH-ONCAB may confer a particular advantage in preventing perioperative myocardial infarction and reducing overall blood loss. Future work should focus on larger matched studies and multicenter randomized controlled trials that risk-stratify patients according to preoperative ventricular function and renal insufficiency to allow us to optimize our surgical revascularization strategy in these high-risk patients.
