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

Postdilatation using the original delivery system balloon at the same filling volume (the double-tap technique) has been proposed to improve balloon-expandable transcatheter heart valve (THV) expansion during transcatheter aortic valve replacement (TAVR); however, its immediate hemodynamic impact remains unclear. Here, we report a case series of 6 consecutive patients who underwent TAVR with balloon-expandable valves in whom the double-tap technique was performed with hemodynamic assessment using a pressure-sensing guidewire. The mean transvalvular pressure gradients and midportion THV diameters were evaluated before and after the double-tap technique. This technique was significantly associated with reduced mean transvalvular pressure gradients (median difference: -6.5 mm Hg; P = 0.036) and increased midportion THV diameter (median difference: 0.8 mm; P = 0.036), whereas paravalvular leak was reduced to trivial or none in all patients, and no cardiovascular death, stroke, or permanent pacemaker implantation occurred at 30 days. The double-tap technique under pressure-sensing guidewire guidance may facilitate safer valve optimization during TAVR.
