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

Background: Coronary obstruction after transcatheter aortic valve implantation (TAVI) is a rare complication typically occurring acutely. Delayed coronary obstruction (DCO) due to early pannus formation is exceptionally uncommon. Case summary: A 74-year-old woman with no coronary artery disease underwent TAVI with a self-expandable 26-mm Evolut Pro + (Medtronic) transcatheter heart valve (THV) six months prior. She presented with recurrent non-ST-segment elevation myocardial infarctions (NSTEMI), despite no angiographic evidence of acute coronary lesions. Multimodality imaging revealed early pannus overgrowth around the THV, causing mechanical obstruction of the left main ostium. Following Heart Team discussion, she underwent successful coronary artery bypass grafting without the need for surgical THV intervention. Discussion: This case highlights a rare cause of DCO post-TAVI. Both orthotopic chimney stenting and THV explant with surgical valve replacement were deemed unsuitable in this context.
