The case is presented of a 68-year-old man who previously had undergone aorta-coronary bypass. During a 3 year interval the coronary disease progressed, so that a once insignificant lesion necessitated reoperation. A Gore-Tex vascular graft was chosen as a substitute because of the lack of saphenous vein. Three months postoperatively the patient's recatheterization study showed patency of the Gore-Tex graft placed in the distal right coronary artery, and there was a satisfactory clinical result. No anticoagulants have been given to the patient after the operation.
