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

backgroundTranscatheter aortic valve implantation (TAVI) is increasingly performed, with TAVI-in-TAVI reinterventions becoming more frequent. Coronary access after TAVI-in-TAVI can be severely limited by neoskirt formation. CASE SUMMARY: A 74-year-old man with extensive comorbidities and prior TAVI-in-TAVI (Evolut and Sapien valves) presented with chest pain and troponin elevation. Angiography showed severe left main artery and left anterior descending artery stenoses, but selective coronary engagement was impossible given complete neoskirt obstruction. Using transcatheter electrosurgery, a Steelcore guidewire insulated in a microcatheter was energized to perforate the neoskirt. Percutaneous coronary intervention with drug-eluting stents was successfully completed, with an excellent final result. DISCUSSION: To our knowledge, this is the first report of electrosurgical neoskirt perforation to enable coronary revascularization after TAVI-in-TAVI. TAKE-HOME MESSAGES: Electrosurgery can safely perforate a neoskirt, restoring coronary access. This novel strategy may become essential as TAVI-in-TAVI procedures increase.
