TAVR Using a Premounted Dry Valve in a Patient With Severe Aortic Stenosis and Tortuous Descending Aorta.
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
backgroundTranscatheter aortic valve replacement (TAVR) with wet tissue valves have several limitations that compromise their durability and lifespan, and it is technically challenging in patients with a tortuous descending aorta. CASE SUMMARY: We report an 81-year-old woman with severe symptomatic aortic stenosis, characterized by a functionally bicuspid aortic valve with extensive calcification, horizontal heart configuration. and tortuous descending aorta. The patient underwent successful transfemoral TAVR using a premounted dry valve system with cerebral embolic protection and a minimalist approach. DISCUSSION: This case confirms the feasibility of long sheath-assisted TAVR using a premounted dry valve system. Given the availability of premounted dry valves in China, the use of a premounted dry valve with potentially enhanced durability was chosen to avoid the risk of reintervention in this elderly patient. TAKE-HOME MESSAGE: Successful TAVR using a premounted dry valve system in patients with complex anatomy requires meticulous preprocedural planning, advanced imaging analysis, and appropriate device selection.
