Abstract: The valve-in-valve (VinV) percutaneous procedure is a valuable alternative for the treatment of failed bioprosthetic surgical heart valves (SHV) in high-risk patients (Dvir et al. 2014). There is a few data about the effect of the position of implantation of the transcatheter heart valve (THV) on the hemodynamic performance of the VinV assembly (Azadani et al. 2009). Until now, no study has focused on the hemodynamic performance of the Medtronic CoreValve (CV) within the St-Jude Medical Trifecta (TF) bioprosthesis. The objective of this in vitro study was to (1) assess hemodynamic performance of the VinV implantation of the CV THV within the TF SHV, (2) evaluate the loss of hemodynamic performance due to VinV and (3) compare different VinV assemblies in order to guide clinicians for the selection and positioning of the CV
