Redo-TAVI with the SAPIEN 3 valve in degenerated calcified CoreValve/Evolut explants

EuroInterventionPublished Mechanistic study

Authors' conclusion

S3 implantation at node 5 in calcified CV/EV valves resulted in satisfactory hydrodynamic performance in most configurations tested with stable leaflet overhang throughout the cardiac cycle.
