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

objectivesOne of the risks of redo transcatheter aortic valve replacement is coronary artery obstruction caused by the cusps of the first transcatheter aortic valve. We evaluated the feasibility of this procedure based on data from post-transcatheter aortic valve replacement computed tomography scans. We also evaluated whether redo transcatheter aortic valve replacement could be a standard lifetime management option for patients with severe aortic stenosis.

methodsThe post-transcatheter aortic valve replacement computed tomography data of 143 patients who received balloon-expandable transcatheter aortic valves and 187 patients who received self-expanding transcatheter aortic valves were analyzed. The risk of coronary obstruction in redo transcatheter aortic valve replacement, defined by the transcatheter aortic valve commissure level above the coronary height and a transcatheter aortic valve-to-aorta distance of < 2.0 mm in each coronary sinus, was evaluated.

resultsThe mean age of the patients was 85.5 ± 5.1 years (35% male), and the mean body surface area was 1.43 ± 0.17 m

conclusionsCurrent transcatheter aortic valve devices may carry a higher risk of coronary obstruction in patients with small aortic roots. Careful patient selection and comprehensive pre-procedural assessment are necessary to reduce the risk for the patients' lifetime management.
