Aortitis, aortic valve incompetence, and left coronary ostium stenosis in a patient with C-ANCA-associated necrotizing vasculitis.

Aortitis with involvement of the aortic valve is rarely associated with vasculitis syndromes. We present a patient with antibodies to a neutrophil cytoplasmic antigen-associated (ANCA) vasculitis with renal failure who developed aortic incompetence as a result of aortitis which involved the aortic valve. Thickening of the aortic wall also caused stenosis of the left coronary ostium.
