title: [A case of aortic valve replacement 3 years after coronary artery bypass grafting].
abstract: A rare case of aortic valve replacement (AVR) with poor left ventricular function, following coronary artery bypass grafting, was reported. The patient was 57-year-old man who received urgent CABG with 2 saphenous vein grafts 3 years ago. At that time, aortic regurgitation (AR) was grade 2. He suffered acute myocardial infarction 1 year after CABG because of the occlusion the saphenous vein graft to the obtuse marginal branch. Percutaneous transluminal angioplasty was successfully performed for occluded graft. Since then, however, AR increased gradually and the left ventricular function decreased. Three years after the initial operation, he was admitted again with congestive heart failure. Heart catheterization revealed grade 3 AR and 17% left ventricular ejection faction (LVEF). AVR was performed through a median sternotomy and 2 saphenous vein grafts were preserved. He showed uneventful postoperative recovery and is now very well with 40% LVEF.
