Why the study?
PPVI success depends on precise valve sizing and optimal hemodynamic performance, prompting the exploration of custom-modified mock loops with patient-specific 3D-printed pulmonary artery geometries to advance pre-implantation planning.
Does patient-specific 3D-printed pulmonary artery modeling improve valve sizing and hemodynamic assessment for percutaneous pulmonary valve implantation?
Population
Patient-specific 3D-printed pulmonary artery geometries of 5 patients who underwent PPVI with Pulsta THV
Comparison
Various Pulsta THV sizes (26, 28, 30, and 32 mm) across different cardiac outputs
Design
In vitro simulation study using a modified ViVitro pulse duplicator system

Supports 3D-printed model use for PPVI hemodynamics; leaves open clinical benefit of alternative sizing.
Does patient-specific 3D-printed pulmonary artery modeling improve valve sizing and hemodynamic assessment for percutaneous pulmonary valve implantation?
Patient-specific 3D-printed models in a mock loop system can accurately simulate hemodynamics and potentially optimize valve sizing for percutaneous pulmonary valve implantation.
