Background: The Inspiris Resilia (Edwards Lifesciences LLC) bioprosthesis has gained widespread use in the aortic position; however no robust data are available about its use in the pulmonary position. Methods: We reviewed our outcomes for the Inspiris Resilia in the pulmonary position between August 2019 and October 2021. Results: Twenty-seven patients (15 female patients [56%]; mean age, 22.26 ± 14.99 years) were included. The most common original pathology was tetralogy of Fallot (13 patients, 48%). Five patients (18.5%) had prior transcatheter interventions. The mean right ventricular end-diastolic volume index was 164.25 ± 45.1 mL/m2. Sternotomy or repeat sternotomy was the most common approach (21 patients, 77.8%). The standard technique for pulmonary valve replacement was used in 22 patients (81.5%), whereas the prosthesis was implanted as a conduit in the remaining 5 (18.5%). Trivial to mild prosthetic regurgitation was present in 6 patients (22.2%) at the time of discharge. There was no early mortality. Follow-up was complete in all patients (mean, 16 ± 8 months), with no late mortality or late reoperations. New prosthetic regurgitation developed in 13 patients (48%), all of whom underwent replacement with the standard surgical technique. No regurgitation occurred in the conduit cases. This progressed to moderate regurgitation in 6 patients (22%) and severe in 3 (11%). Three patients (11%) underwent transcatheter valve-in-valve after their surgical pulmonary valve replacement. Conclusions: The early data regarding the Inspiris Resilia bioprosthesis use in the pulmonary position is concerning. The prosthesis design may not be suitable for low-pressure circulation, or modification of its implantation technique may be needed.
