Considering the intrinsic limitations of the OBSERVANT study, we found that patients undergoing TF-TAVI with a supra-annular SE valve had a higher all-cause mortality compared to those receiving an intra-annular BE valve at 5 years. A late catch up phenomenon of patients receiving the BE valve was observed beyond 3 years. Post-procedural moderate/severe PVR seems to play a crucial role in determining this finding. Comparative studies of new generation devices with longer follow-up are needed to evaluate the benefit of each specific TAV type.
