Redo TAVI: Improved Hemodynamics With a Supra-Annular Valve in a Small Annulus.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundExpanding 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 procedural and hemodynamic success. The Redo TAVI app by Dr Bapat is an essential aid, and the Allegra THV a useful consideration in redo TAVI procedures with small annuli.
