Case Report: Endothelialized but unstable: late migration of a ventricular septal defect closure device.

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
Late device migration following transcatheter perimembranous ventricular septal defect (VSD) closure is exceedingly uncommon, as most cases of embolization occur within the first hours to weeks after implantation. In the present case, migration was observed 18 months post-procedure, representing an unusually late presentation. Notably, surgical retrieval demonstrated complete circumferential endothelialization of the device, confirming true long-term tissue incorporation before subsequent erosion and detachment. Furthermore, serial early and mid-term imaging consistently showed a stable device position, making early malposition or technical error an unlikely cause. This constellation of findings underscores the rarity of very late mechanical destabilization after an initially successful device closure.
