Transcatheter Aortic Valve Replacement in Aortic Regurgitation Secondary to Aortic Valvulitis.
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
objectivesTo evaluate the feasibility of off-label transcatheter aortic valve replacement in a 29-year-old man with severe aortic regurgitation (AR) who was not a surgical candidate because of systemic vasculitis. KEY STEPS: The right radial artery was unsuitable because of small caliber and spasm, and the right common iliac artery was occluded, necessitating femoral access with serial dilation. The device was positioned under angiography and deployed during rapid pacing, with subsequent hypotension requiring resuscitation. Postprocedure, hemodynamics improved (mean gradient 3 mm Hg, no regurgitation). Arteriography revealed a left common iliac artery dissection, which was stented. Three-month follow-up confirmed appropriate valve positioning/function. POTENTIAL PITFALLS: In pure AR, lack of annular/leaflet calcification-especially in younger patients-can impair anchoring. Vasculitis further complicates sizing/deployment and can limit access. Rapid pacing in poorly functioning ventricles carries a risk for cardiac arrest. Long-term durability of transcatheter aortic valve replacement in young patients remains uncertain, and its use for native AR in the United States remains off-label.
