[A case of emergency replacement of SAM disk valve prosthesis for disk detachment]

A 47-year-old patient had undergone the mitral valve replacement using a SAM disk prosthesis in 1977. 15 years and 10 months after the first operation, she successfully underwent emergency replacement with a St. Jude Medical valve prosthesis because of detachment of the disk of the SAM prosthesis and now she is doing well.
