Effective treatment of hypertrophic cardiomyopathy with left ventricular outflow tract obstruction using a covered stent.
Article in BMJ case reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
A woman in her 60s presented with progressive exertional dyspnoea, exertional chest pressure and exertional dizziness. Echocardiogram identified a 156 mm Hg left ventricular outflow tract gradient with provocation, indicating hypertrophic cardiomyopathy with left ventricular outflow obstruction-confirmed with MRI and angiogram. An alcohol septal ablation was planned but due to communication of the second septal perforator with the right ventricle and a wire-induced mid-left anterior descending artery dissection, alcohol septal ablation was not performed. Instead, a covered stent was placed in the mid-left anterior descending artery covering the origins of the third and fourth septal perforators. The left ventricular outflow tract gradient decreased from 90 to 30 mm Hg with provocation and her symptoms improved. Follow-up showed a left ventricular outflow tract gradient of 35 mm Hg with provocation and decreased symptoms.
