Structural Valve Failure During Transcatheter Aortic Valve Replacement: Infolding, Deformation, Embolization, and Valve-In-Valve Rescue.

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
objectivesInfolding, deformation, and embolization are forms of valve failure linked to significant complications. We report a successful same-procedure bailout redo-transcatheter aortic valve placement (redo-TAV) approach after failure of the index transcatheter aortic valve replacement. KEY STEPS: An Evolut 34-mm valve showed infolding with vertical-line sign after deployment. Postdilatation with a NuMED 25-mm balloon caused deformation, embolization, and significant aortic regurgitation. Bailout redo-TAV rescue with a second Evolut 34-mm valve was positioned around 1-mm deeper. Final postdilatation with a NuMED 26-mm balloon resolved paravalvular leak and gradients and improved the transcatheter heart valve configuration. COMPLICATION PREVENTION STRATEGY: Careful verification of proper Evolut valve loading prior to insertion-along with timely recapture, resheathing, and retrieval before final deployment when abnormalities are identified-could have prevented this complication. Tall-in-tall redo-TAV may impair coronary reaccess and increase coronary obstruction risk. TAKE-HOME MESSAGE: Early detection of misloading and infolding is essential to prevent severe transcatheter heart valve deformation and may help avoid the complications related in the case.
