title: Isolated coronary ostial stenosis in Takayasu's arteritis: case report and review of the literature.
abstract: This report describes a rare clinical course of a young Japanese woman with Takayasu's arteritis and a review of the literature. Her first symptom was angina pectoris due to isolated left coronary ostial stenosis, which was relieved by aortocoronary bypass grafting surgery using a saphenous vein graft. At that time, the C-reactive protein was negative and the histopathologic findings of the specimens of the aorta could not confirm aortitis. Although she was free from any cardiovascular symptoms for about fifteen years, syncopal attacks occurred owing to severe stenosis of the major branches of the aortic arch revealed by intravenous digital subtraction arteriograms. Thus, Takayasu's arteritis could be a cause of coronary ostial stenosis in young women even if the inflammatory findings are negative and the major branches of the aortic arch are not involved at operation. In addition, revascularization using internal thoracic arteries might possess a potential risk of coronary insufficiency due to a later involvement of these proximal arteries.
