[Mitral annuloplasty ring dehiscence after blunt chest trauma].

A case of recurrent severe mitral regurgitation following blunt chest trauma with deceleration injury in a 61-year-old woman is presented. The patient had undergone previous CABG and mitral annuloplasty with the use of a flexible (Duran) ring. At reoperation, partial dehiscence of the annuloplasty ring, which had become rigid, was found. This was successfully repaired.
