Revascularization for coronary ostial stenosis in Takayasu's disease with calcified aorta.

A case in which a patient with stenoses of the right and left coronary ostia and heavy calcification of the aorta caused by Takayasu's disease was successfully treated by coronary artery bypass grafting is presented. The aortic ends of the two grafts were attached to a xenopericardial patch, which was sutured into the ascending aorta. This technique can be done without fine sutures, which are required for proximal anastomosis of a vein graft, and may reduce the risk of ostial stenosis.
