Abstract:
Percutaneous pulmonary valve implantation is a less invasive procedure to treat right outflow tract dysfunction related to surgical procedures such as repair of Tetralogy of Fallot. Despite the lower risks, complications have been reported, namely embolisation of the pre-stent. We report a case of a 16-year-old boy, whose procedure was complicated by embolisation of the pre-stents and the strategy used to reimplant them, prior to the successful implantation of a pulmonary valve.
