摘要：A 72-year-old woman, underwent aortic valve replacement(AVR) with a ball valve 35 years ago after the diagnosis of aortitis syndrome and aortic valve regurgitation. She developed unstable angina with 90% stenosis lesion of the left main trunk(LMT) ostium. We decided to carry out revascularization surgery since the strut of the ball valve was considered to be an obstacle to percutaneous coronary intervention. Using upper abdominal median and left anterolateral approachs, Off-pump coronary artery bypass grafting was performed with the right gastroepiploic artery grafting to the left anterior descending artery. The patient was discharged from the hospital on 17 post operative day without any sequalae.
