Objectives To describe a new modification, the one‐step procedure, that allows interventionists to pre‐stent and implant a Melody valve simultaneously. Background Percutaneous pulmonary valve implantation (PPVI) is the standard of care for managing patients with dysfunctional right ventricular outflow tract, and the approach is standardized. Methods Patients undergoing PPVI using the one‐step procedure were identified in our database. Procedural data and radiation exposure were compared to those in a matched group of patients who underwent PPVI using the conventional two‐step procedure. Results Between January 2016 and January 2017, PPVI was performed in 27 patients (median age/range, 19.1/10–55 years) using the one‐step procedure involving manual crimping of one to three bare metal stents over the Melody valve. The stent and Melody valve were delivered successfully using the Ensemble delivery system. No complications occurred. All patients had excellent hemodynamic results (median/range post‐PPVI right ventricular to pulmonary artery gradient, 9/0–20 mmHg). Valve function was excellent. Median procedural and fluoroscopic times were 56 and 10.2 min, respectively, which significantly differed from those of the two‐step procedure group. Similarly, the dose area product (DAP), and radiation time were statistically lower in the one‐step group than in the two‐step group ( P  < 0.001 for all variables). After a median follow‐up of 8 months (range, 3–14.7), no patient underwent reintervention, and no device dysfunction was observed. Conclusions The one‐step procedure is a safe modification that allows interventionists to prestent and implants the Melody valve simultaneously. It significantly reduces procedural and fluoroscopic times, and radiation exposure.
