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

Balloon aortic valvuloplasty (BAV) has played a limited role in the management of patients with severe aortic stenosis. However, BAV is being performed more frequently these days with the emergence of transcatheter aortic valve implantation (TAVI). We previously described a technique named "looped Inoue balloon technique" to simplify the antegrade transvenous BAV by making a loop in the left atrium using two stylets. We present a case in which the looped Inoue balloon technique was successfully applied. The patient was an 83-year-old woman with progressive dyspnea due to severe aortic stenosis. The aortic valve area was 0.39 cm(2) with a mean transvalvular gradient of 46 mmHg. The patient was deemed high risk for surgical aortic valve replacement or TAVI in view of the multiple comorbidities and frailty. Antegrade BAV using the looped Inoue balloon technique was performed. The procedure was successful without any complications. The post procedural aortic valve area increased to 1.15 cm(2) with a mean pressure gradient of 23 mmHg. This is the first report of clinical use of the looped Inoue balloon technique for antegrade BAV.
