TCT-669 Valve-in-Valve in Small Surgical Valves: Predictors for Survival and Elevated Post Procedural Gradients. Insights from the Valve-in-Valve International Data (VIVID) Registry

Small surgical valves are associated with higher mortality after valve in valve (ViV) implantation. We aimed to identify key predictors of elevated post- procedural gradients and mortality in this challenging patient population. A total of 1,565 patients that underwent aortic ViV from the Valve in
