3D Modeling of Self-Expandable Valves for PPVI in Distinct RVOT Morphologies

This study assesses the Pulsta THV® valve’s in vitro hemodynamic performance across these RVOT morphologies using 3D-printed models. For this study, valves were tested using the ViVitro Pulse Duplicator System (ViVitro Labs Inc., Victoria, BC), a system designed to simulate physiological conditions as used in previous studies. Our experiments demonstrated that the larger valve size consistently had lower regurgitation rates across all cardiac outputs.
