The commonly used valve‐in‐valve (VIV) app recommends sizing based on dimensions of both the transcatheter heart valve (THV) and bioprosthetic surgical valve. The implications of hydrodynamic testing to guide VIV sizing are poorly understood. This bench study assessed the hydrodynamic performance of different sizes of self‐expanding supra‐annular THVs in three different surgical aortic bioprostheses at different implantation depths.
