A 64-year-old male patient with pheochromocytoma underwent an off-pump coronary artery bypass graft- ing. Determination of order of surgeries, preoperative medical management and intraoperative hemodynamic management are important in these cases. Al- though bolus administration of phenylephrine showed poor response, the surgery was uneventful and the patient remained hemodynamically stable throughout the procedure and perioperative period.

Heparin rebound in patients undergoing off-pump coronary artery bypass grafting surgery: a single-center retrospective study.
J Cardiothorac Surg
January 2025
Department of Anesthesiology, Fuwai Hospital, National Center for Cardiovascular Diseases, Peking Union Medical College and Chinese Academy of Medical Sciences, No. 167, Beilishi Road, Xicheng District, China.
Background: Heparin, an anticoagulant used in cardiac surgery, can result in heparin rebound (HR), where it returns postoperatively despite being neutralized with protamine. This study was designed to investigate the prevalence of HR in patients undergoing off-pump coronary artery bypass grafting (OPCAB) and evaluate the impact of HR on their short-term outcomes.
Methods: HR was defined by a 10% increase in activated coagulation time (ACT) following two hours of heparin neutralization with protamine, bleeding over 200 mL/h, and abnormal laboratory coagulation examination results.
A Rare Case of Early Left Ventricular Thrombus Development After Off-Pump Coronary Artery Bypass Grafting for Unstable Angina Pectoris With Reduced Left Ventricular Ejection Fraction.

Left ventricular (LV) thrombus is a serious complication of myocardial infarction (MI) that can lead to a fetal systemic embolism. Although coronary artery bypass graft surgery (CABG) after MI is widely performed, to our knowledge, there are no reports of LV thrombus in the early postoperative period. Here, we report a rare case of a 70-year-old man who underwent off-pump coronary artery bypass grafting (OPCAB) for unstable angina pectoris with reduced left ventricular ejection fraction (LVEF).

Background: The impact of seasonal patterns on the mortality and morbidity of surgical patients with cardiovascular diseases has gained increasing attention in recent years. However, whether this seasonal variation extends to cardiovascular surgery outcomes remains unknown. This study sought to evaluate the effects of seasonal variation on the short-term outcomes of patients undergoing off-pump coronary artery bypass grafting (OPCABG).

- This study examines the role of serum uric acid (SUA) levels in patients undergoing off-pump coronary artery bypass (OCABG) surgery, focusing on their impact on postoperative complications like acute kidney injury (AKI).
- The research involved 144 patients and found that 20% experienced AKI, with higher preoperative SUA levels significantly linked to increased risk (OR: 2.04).
- Additionally, elevated SUA levels correlated with longer hospital stays and a higher mortality rate (up to 13% in high SUA patients), indicating that SUA is a crucial predictor for postoperative outcomes.
Early Postoperative Outcome of Continuous Heparin Infusion versus Intermittent Intravenous Heparin after Initial Bolus Dose during Off-Pump Coronary Artery Bypass Surgery: An Eminent Time worthy Study.

Heparin is an anticoagulant used invariably in all cardiac surgery. Heparin dosing and its reversal were determined by monitoring activated clotting time (ACT). Intermittent heparin dosing after initial bolus dose is widely practiced to maintain ACT level 200-300 seconds in Off-pump coronary artery bypass surgery (OPCAB).
