title: Balloon dilatation of a stenosed bioprosthesis in the tricuspid valve position.
abstract: Percutaneous balloon dilatation of a stenosed Ionescu-Shiley bioprosthesis in the tricuspid valve position was performed twice in a 19 year old woman. On each occasion there was a considerable improvement in symptoms and haemodynamic function but the effect lasted for only a few months. When the valve was excised it showed no evidence of the previous balloon dilatations.
