Transcatheter Aortic Valve Implantation via the Right Subclavian Artery for Chronic Type A Aortic Dissection.

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 implantation (TAVI) in patients with chronic type A aortic dissection (CTAAD) is rare, and the optimal strategy remains undefined. CASE SUMMARY: An 86-year-old woman with symptomatic severe aortic stenosis underwent preprocedural computed tomography for TAVI before scheduled gastric cancer surgery, revealing CTAAD. To avoid the dissection flap, the right subclavian artery was selected as the access route, and a balloon-expandable valve was successfully implanted. DISCUSSION: The dissection cavity was located along the outer curvature of the ascending aorta. The right subclavian artery approach allowed effective avoidance of the dissection cavity. Balloon-expandable valves are less likely to interact with the dissection flap. Therefore, using a balloon-expandable valve via the right subclavian artery represents a favorable strategy for TAVI in patients with CTAAD. TAKE-HOME MESSAGE: TAVI using a balloon-expandable valve via the right subclavian artery is an effective strategy for managing complex cases involving CTAAD.
