Aims: Multiple surgical revisions are often necessary in individuals with congenital heart defects affecting the RVOT or pulmonary valve. There are no multicentre data on the feasibility and safety of percutaneous pulmonary valve implantation (PPVI) using the SAPIEN 3 (S3) transcatheter heart valve. The aim of this study was to explore the short-term safety, feasibility, and haemodynamic outcomes of PPVI using the S3 transcatheter heart valve. Methods and results: Pulmonic S3 is an observational registry of patients undergoing PPVI with the S3 valve across centres in Europe and Canada. Data for 82 patients (mean age 27.3 years) were obtained. The most common underlying diagnosis was tetralogy of Fallot (ToF) (58.5%), with 16.0% of patients having native RVOT anatomy;90.2% received pre-stenting. Prosthesis dislodgement occurred in one patient and conduit perforation in another. Both were successfully resolved without the need for open surgery. Peak systolic gradient over the RVOT fell from 46.3 mmHg to 17 2 mmHg, moderate/severe pulmonary regurgitation from 86.3% to 0.0%, and NYHA >= II from 86.0% to 15.2%. During follow-up, valve thrombosis was observed in two patients which resolved with adequate anticoagulation. No other procedural complications, endocarditis, stent fracture or death were reported within two years. Conclusions: PPVI with the S3 valve appears feasible and safe in a wide range of patients with congenital heart defects, with good short-term haemodynamic and functional outcomes.
