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

ABSTRACT:

Background

Redo-transcatheter aortic valve implantation (TAVI) is the treatment of choice for failed transcatheter aortic valves. Currently, implantation of a SAPIEN 3 (S3) is indicated for redo-TAVI in degenerated CoreValve/Evolut (CV/EV) transcatheter aortic valves (TAVs) but is not well understood.

Aims

We aimed to evaluate S3 function following implantation in explanted calcified CV/EV TAVs and to assess the impact of CV/EV pathology on redo-TAVI outcomes.

Methods

Ex vivo hydrodynamic testing was performed per the International Organization for Standardization (ISO) 5840-3 standard on 4 S3 TAVs implanted at node 5 in calcified CV/EV explants. The mean gradient (MG), effective orifice area (EOA), peak velocity, regurgitant fraction (RF), geometric orifice area (GOA
