Percutaneous replacement of the pulmonary valve in a right ventricle to pulmonary artery (RV-PA) conduit using bovine jugular valves has recently been described as an alternative to surgical options in selected patients weighing >or=20 kg. We report the first case of transcatheter pulmonary valve implantation in an infant and the first use of "off the shelf" components. A 12-mm (Hancock) porcine valve was sutured into a predilated Genesis 2510b stent. The valved stent was manually crimped and mounted on a 12-mm balloon. Snare-assisted deployment in the middle of the RV-PA conduit was accomplished without the use of a long sheath. After the initial deployment, a 14-mm balloon was used to further approximate the stent to the walls of the conduit. Short-term (11 month) follow-up has demonstrated continued valve integrity, markedly decreased right ventricular size and improved function and symptomatic improvement. At 10 months of age, this case represents the youngest patient to undergo percutaneous valve placement and documents the technical feasibility of the procedure.
