Key result
The Pulsta THV valve demonstrated optimal hemodynamic performance in RVOT Types 1 and 2, while Types 3 and 5 exhibited increased pressure gradients and hemodynamic variability.
Why the study?
PPVI with self-expandable valves offers an alternative for enlarged RVOTs, but the in vitro hemodynamic performance across distinct patient RVOT morphologies needed assessment.
Does the Pulsta THV valve improve hemodynamic performance in specific 3D-printed RVOT morphologies of Tetralogy of Fallot patients?

In vitro performance data across RVOT types support further device evaluation; leaves open clinical PPVI adoption in TOF.
Does the Pulsta THV valve improve hemodynamic performance in specific 3D-printed RVOT morphologies of Tetralogy of Fallot patients?
In vitro testing of the Pulsta THV valve in 3D-printed RVOT models suggests optimal hemodynamic performance in Types 1 and 2 morphologies, highlighting the importance of pre-procedural anatomical planning for percutaneous pulmonary valve implantation.
Ödemiş et al. (2025) studied Tetralogy of Fallot / Right ventricular outflow tract (RVOT) morphologies (n=195). Pulsta THV valve was evaluated on Hemodynamic performance (regurgitation rates and pressure gradients). The Pulsta THV valve demonstrated optimal hemodynamic performance in RVOT Types 1 and 2, while Types 3 and 5 exhibited increased pressure gradients and hemodynamic variability.
