title: Reoperation of the Kay-Shiley disc valve 35 years after replacement.
abstract: The Kay-Shiley disc valve (Shiley Inc, Irvine, CA) was manufactured in 1965 and is no longer in clinical use due to its high incidence of thromboembolism. We report a case of tricuspid valve replacement with the Kay-Shiley valve 35 years previously. The valve was replaced successfully with a St. Jude Medical valve (St. Jude Medical, Inc, St. Paul, MN). This is the longest interval from implantation to re-replacement with the Kay-Shiley valve that has been reported in the literature.
