Severe aortic regurgitation secondary to idiopathic aortitis

Clinical and morphologic features are described in two relatively young adults with aortic regurgitation secondary to chronic aortitis. The regurgitation in each was severe enough to require aortic valve replacement. Both patients had normochromic, normocytic anemia, considerable weight loss despite congestive cardiac failure, and negative serologic tests for syphilis. These systemic manifestations in association with the aortitis suggest that both had Takayasu's arteritis. In addition, one patient had total occlusion at the origin of one subclavian artery (classic pulseless disease). Takayasu's arteritis must be added to the list of causes of severe aortic regurgitation.
