  Figure 1. Predictive model valve-in-valve (ViV). Annual model forecast output from the simulation. Annual total ViV volume (green curve) matches observed TVT registry data (purple squares) and is composed of the summation of the TAVR-in-TAVR (blue curve) and TAVR-in-SAVR (yellow curve). Redo procedure trends for SAVR-after-SAVR (black diamonds) and SAVR-after-TAVR (gray triangles) are also plotted. For total ViV in 2035, standard deviation = 240 cases. Abbreviations: SAVR, surgical aortic valve replacement; TAVR, transcatheter aortic valve replacement; TVT, Transcatheter Valve Therapies.
