Aims: Percutaneous pulmonary valve implantation (PPVI) is used to treat patients with dysfunctional pulmonary valve conduits. Short-and longer-term results from multiple trials have outlined haemodynamic improvements. Our aim was to report the long-term results, including quality of life, from a multicentre trial in Europe and Canada. Methods and results: From October 2007 to April 2009, 71 patients (24 female; median age 19.0 [IQR: 14.0 to 25.0] years) were enrolled in a prospective cohort study. PPVI was performed successfully in 63 patients. At five-year follow-up four patients had died. Moderate and severe pulmonary regurgitation were completely resolved in all except one patient, who needed re-PPVI. Outflow tract obstruction improved significantly from a mean pressure gradient of 37.7±12.1 mmHg before PPVI to 17.3±9.7 mmHg at five-year follow-up; however, 11 patients needed treatment for restenosis. The EQ-5D quality of life utility index and visual analogue scale scores were both significantly improved six months post PPVI and remained so at five years. Conclusions: Five-year results following PPVI demonstrate resolved moderate or severe pulmonary regurgitation, improved right ventricular outflow tract obstruction, and improved quality of life.
