title: Percutaneous coronary intervention for left main trunk ostial stenosis in a patient with Takayasu's arteritis.
abstract: Takayasu's arteritis with coronary artery involvement is a rare event especially in men. We will report on a male case of Takayasu's arteritis undergoing stent implantation for left main trunk (LMT) ostial stenosis. The case was that of a 25-year-old man who had been diagnosed with Takayasu's arteritis but there was no significant large vessel involvement. He presented with effort angina and a multidetector computed tomography (MDCT) revealed severe ostial stenosis in the LMT. A coronary angiography confirmed this finding and a virtual histology intravascular ultrasound (VH-IVUS) showed fibrous thickening of the intima and media with little necrotic lipid core and calcification. We performed a bare metal stent implantation for this lesion. No restenosis was found in the MDCT at the 6 month follow-up. Our experience suggests that the VH-IVUS is useful for examining the gross structure and component of the coronary vascular wall and for determining the choice of treatment in patients with Takayasu's arteritis.
