Snare-Assisted Transseptal Antegrade Transcatheter Aortic Valve Replacement: Turning Back the Clock.
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
backgroundTransfemoral access remains the preferred route for transcatheter aortic valve replacement (TAVR); however, severe peripheral artery disease (PAD) and unfavorable anatomy can result in the preclusion of conventional access. Transseptal antegrade TAVR may offer another avenue in such cases. CASE SUMMARY: An 81-year-old man with severe symptomatic aortic stenosis, extensive peripheral artery disease, porcelain aorta, prior coronary artery bypass graft, and prohibitive surgical risk had no feasible conventional access. As such, a transseptal antegrade TAVR approach was pursued. During advancement of a balloon-expandable valve system through the left atrium and mitral valve, navigation toward the aortic annulus was difficult. Retrograde snare capture of the valve nose cone enabled traction, coaxial positioning, and successful deployment of a 29-mm SAPIEN 3 Ultra RESILIA valve with excellent hemodynamics and trace paravalvular regurgitation. DISCUSSION: Retrograde snare assistance facilitated valve delivery when antegrade advancement was insufficient. TAKE-HOME MESSAGE: In carefully selected patients, transseptal antegrade TAVR with retrograde snare-assisted delivery may be an alternative strategy.
