Isolated left coronary ostial stenosis as the sole arterial involvement in Takayasu's disease

Abstract

A 24-year-old woman with Takayasu's disease developed unstable angina pectoris. Angiographic studies demonstrated an isolated left coronary ostial stenosis without any other systemic arterial involvement. She is unique in that the coronary lesion, which is rarely the major manifestation of Takayasu's disease, is the sole arterial involvement of the disease.
