Endovascular implantation of a Melody valve in the mitral position with extracorporeal membrane oxygenation support in a pediatric patient.
Article in Annals of pediatric cardiology. 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
Reoperation for dysfunctional mitral bioprostheses carries substantial risk. Endovascular valve-in-valve (V-in-V) implantation is an alternative, but pediatric experience is scarce. We report the feasibility of the Melody valve V-in-V with elective extracorporeal membrane oxygenation (ECMO) support in an inoperable pediatric patient. A transvenous antegrade, transesophageal echocardiography-guided procedure was performed with venoarterial ECMO. The transmitral gradient fell from 30 to 8 mmHg without paravalvular leak or left-ventricular outflow obstruction. ECMO was discontinued within 24 h. At 3-year follow-up, valve function remains preserved, and the patient is stable. Melody V-in-V with elective ECMO is a viable rescue strategy for high-risk pediatric candidates.
