Mitral-aortic intervalvular fibrosa involvement by takayasu' arteritis.

Takayasu's arteritis is an inflammatory disease with a variety of manifestations, such as cardiac involvement. We describe a 52-year-old woman with clinical and echocardiographic manifestations mimicking infectious endocarditis, such as periaortic and mital-aortic intervalvular fibrosa abscess with extension to the anterior mitral leaflet. However, no infective tissue was discovered intraoperatively. Pathological evaluation demonstrated Takayasu's arteritis. To the best of our knowledge, Takayasu's arteritis can involve mitral-aortic intervalvular fibrosa and imitate infectious endocarditis.
