We report an extremely rare case of fibrous tissue overgrowth 3 years after mitral valve repair using a mitral annuloplasty ring in a 53-year-old woman who underwent mitral valve replacement for mitral stenosis. Whitish fibrous tissue had overgrown from the ring on the atrial side of the annulus, and had severely reduced the valvular area. However, the motion of the mitral leaflets was not restricted. Considering the presence of concomitant aortitis syndrome, it is strongly suggested that the overgrowth of fibrous tissue was promoted as a reaction to chronic inflammation.
