TCT-162 Surgical Bioprosthesis Size Definition and Hemodynamic Performance following Aortic Valve-in-Valve: Insights from the Valve-in-Valve International Data (VIVID) Registry

Transcatheter valve-in-valve (ViV) implantation is an alternative for the treatment of patients with degenerated bioprostheses. However, elevated post-procedural gradients are common following aortic ViV and are more common in small label sized surgical valves. Thus far the impact of surgical
