Takayasu's arteritis is a chronic inflammatory arteriopathy. It mainly affe
cts the aortic arch and its main branches. The aortic valve annulus and cor
onary and pulmonary arteries are rarely affected. Mitral and tricuspid annu
lar calcification were not reported previously. We identified mitral annula
r calcification by using transthoracic echocardiography in 3 patients with
Takayasu's arteritis, in whom none had any of the reported causes of mitral
annular calcification. Two of them had concomitant tricuspid and aortic an
nular calcification.
