Commissural Alignment During TAVR With a New-Generation Self-Expandable Valve in a Single Coronary Artery.
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) in patients with a single coronary artery (SCA) is challenging because loss of coronary access may have catastrophic consequences. CASE SUMMARY: A 92-year-old woman with severe aortic stenosis underwent transfemoral TAVR. Preprocedural computed tomography revealed an SCA arising from the left coronary cusp with a small annulus. TAVR was performed using an Evolut FX+ valve with intentional commissural alignment guided by cusp-overlap and en face fluoroscopic views. Postprocedural imaging demonstrated preserved coronary access and flow, with a large stent-frame cell facing the coronary ostium. The patient recovered uneventfully. DISCUSSION: Intentional commissural alignment with imaging-guided deployment may preserve coronary access without coronary protection in patients with complex coronary anatomy. TAKE-HOME MESSAGE: Intentional commissural alignment may facilitate safe TAVR while preserving coronary access in patients with SCA.
