Risk Factors for Conversion to Cardiopulmonary Bypass During Off-Pump Coronary Artery Bypass Surgery

Recognition of the preoperative risk factors associated with an increased risk of conversion may allow for better patient selection and reduce the incidence of intraoperative conversion during OPCAB.
