In this brief report, the authors present an ex vivo bench study evaluating the impact of post-dilation strategies on Evolut FX+ transcatheter heart valves (23, 26, 29, and 34 mm). Valves were expanded in an elliptical annular model and underwent post-dilation using balloons either within or exceeding the instructions for use recommendations. Instructions for use-guided post-dilation preserved frame geometry, caused no leaflet damage, and maintained the regurgitant fraction below thresholds (
