Inadvertent Left Ventricular Implantation of a Leadless Pacemaker Managed by Percutaneous Extraction.
Article in JACC. Case reports, 2026. 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
backgroundAlthough leadless pacemakers minimize lead- and pocket-related complications, their implantation requires a precise technique to avoid rare but serious malposition events. CASE SUMMARY: We present an 84-year-old woman with inadvertent left ventricular (LV) implantation of an Aveir leadless pacemaker. The device was successfully extracted using a carefully executed double-snare technique, followed by new device implantation in the right ventricle. DISCUSSION: There is limited literature guiding the management of inadvertent LV leadless pacemaker implantation, particularly regarding anticoagulation and safe extraction strategies. This case highlights key considerations and demonstrates a successful approach to device removal. TAKE-HOME MESSAGES: As the use of leadless pacemakers increases, so does the potential for related complications, including inadvertent LV implantation. Using multiple fluoroscopic projections during implantation can help ensure correct right ventricular positioning. If LV placement occurs, management-including consideration of anticoagulation and tailored extraction strategies-should be individualized to reduce thromboembolic risk.
