title: Traumatic ostial stenosis of internal mammary coronary graft.
abstract: Because of the extensive use of arterial conduits for coronary surgery there is a growing interest in percutaneous intervention in these conduits. This kind of intervention presents a challenge for the interventional cardiologist owing to the anatomic and functional characteristics of this graft. In most cases significant internal mammary artery disease occurs at the distal anastomosis. Ostial stenoses are rare and their pathology uncertain. The authors report a case of an ostial graft lesion, most probably caused by repetitive ostial engagement of the left internal mammary artery in combination with atherosclerosis in the subclavian artery affecting the internal mammary artery.
