Background: Coronary artery bypass grafting (CABG) is a frequently performed surgery worldwide. The classical coronary bypass surgery performed with the heart stopped and using heart-lung machine is called as on-pump CABG, whereas the coronary bypass surgery performed without stopping the heart or using heart-lung machine is called as off-pump CABG. It is thought that generally respiratory complications can occur during extubation stress in the patients undergoing off-pump CABG performed with fast-track protocol. Case Report: We report a 56 year old patient with 75% stenosis in left anterior descending and circumflex artery. He developed bradycardia after coronary artery bypass grafting by off-pump technique. His repeat angiography showed stenotic right coronary artery after than it was corrected by percutaneous transluminal coronary angioplasty and stent implantation Conclusion: The probability of development of different clinical situations should be kept in mind and the patient should be re-explored without hesitating in case of any hemodynamic instability. Herein, I intended to discuss a different specific case.
