Aortic valve regurgitation as the presenting sign of Takayasu arteritis.

Takayasu arteritis is a rare chronic vasculitis primarily involving the aorta and its main branches. We report an adolescent girl with Takayasu arteritis who presented with an isolated aortic valve regurgitation as part of a systemic inflammatory process. This patient was initially misdiagnosed as having rheumatic heart disease and the correct diagnosis was made only 1 year later.

Conclusions: Takayasu arteritis should be considered among the diagnostic possibilities in patients who present with an unexplained systemic inflammatory syndrome and a cardiac murmur.
