Noninfective endocarditis in microscopic polyangiitis: Report of a case with a successful response to immunosuppressive therapy.

Although antineutrophil cytoplasmic antibody (ANCA) vasculitis has a variety of clinical manifestations, valvular compromise is not common, especially in anti-myeloperoxidase (anti-MPO) antibody (perinuclear [P]-ANCA) vasculitis. We report the case of a 38-year-old woman with ANCA-associated vasculitis who was diagnosed with valve vegetation, that resolved with immunosuppressive therapy.
