Rescuing a Popped-Up Prosthesis: Redo TAVI Using a Novel Snaring and Balloon Displacement Technique.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveWe report the successful management of a 30-mm Hydra self-expanding tall-frame transcatheter heart valve (THV) pop-up through a redo TAVI procedure. KEY STEPS: A new Safari extra-stiff guidewire was advanced externally in respect of a 30-mm Hydra valve frame. A 25-mm Amplatz Goose Neck snare was manipulated to engage the proximal arches of the Hydra THV. In parallel, a 12 × 40 mm Atlas Gold high-pressure balloon was positioned between the Hydra valve frame and ascending aorta, and was then inflated while a new Edwards Sapien 3 Ultra 23-mm valve was advanced and eventually successfully deployed. POTENTIAL PITFALLS: Although index THV pop-up was favored by pacing loss of capture during balloon postdilation, the lack of an external sealing skirt in the Hydra THV system may have increased its susceptibility to migration during balloon maneuver, as occurred in our case. TAKE-HOME MESSAGE: To our knowledge, this is the first reported case describing the use of this combined technique to address embolization of a self-expanding tall-frame THV, resulting in an effective and safer procedure.
