1 · What the graph read from it

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.

2 · The registry

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

backgroundCoronary artery obstruction after transcatheter aortic valve replacement (TAVR) is a rare but life-threatening condition. A bailout strategy has not yet been standardized. CASE SUMMARY: A 91-year-old woman underwent TAVR with a self-expanding valve. Shortly after an initially uneventful procedure, she developed cardiac arrest due to subacute occlusion of the right coronary artery. Although the right coronary sinus was sequestered by the transcatheter heart valve, selective right coronary artery access was achieved via a "roundabout" approach from the noncoronary cusp. Two overlapping zotarolimus-eluting stents across the native commissure restored coronary flow, with satisfactory midterm patency. DISCUSSION: The mechanisms of coronary artery obstruction and the spatial relationship between the native valve and transcatheter heart valve vary according to patient anatomy and device configuration, necessitating tailored bailout strategies after TAVR. TAKE-HOME MESSAGE: A "roundabout" approach via the adjacent cusp may allow coronary access and revascularization when the coronary sinus is sequestered.
