Reoperation for aortic valve stenosis due to severe calcification of the bioprosthetic valve after modified Bentall operation in Takayasu arteritis.

Takayasu arteritis is an inflammatory disease that affects the aorta and its main branches. The dilation of the aortic root would cause aortic regurgitation (AR). We would demonstrate the dramatic change of the bioprosthesis implanted in the young woman with Takayasu arteritis, which has not been reported previously, and we believe that bioprosthesis should not be implanted easily in Takayasu arteritis.
