A case of Takayasu's aortitis with severe bilateral coronary ostial stenosis is re-ported. A transaortic coronary endarterectomy was performed and sufficient patency was confirmed angiographically 9 years after the operation. This is the first report of late coronary angiography after a transaortic coronary ostial endarterectomy in Takayasu's aortitis. The efficacy of this procedure for coronary ostial stenosis in Takayasu's aortitis is emphasized.
