Redo TAVI: Improved Hemodynamics With a Supra-Annular Valve in a Small Annulus.

ABSTRACT:

Background

Expanding transcatheter aortic valve implantation (TAVI) indications to include severe aortic stenosis patients at a younger age, combined with increasing patient survival, have led to a rise in Redo TAVI procedures. In them, patients with a small native annulus pose a unique challenge.

Case summary

We describe such a patient who presented with early transcatheter heart valve (THV) failure and underwent redo TAVI with an Allegra THV, with an emphasis on redo TAVI planning concepts & process.

Discussion

The Allegra THV's distinctive design allows for higher effective orifice areas in small annuli while commissural post movement owing to a flexible outflow reduce leaflet stress.

Take-home messages

Redo TAVI procedures require meticulous CT analysis for
