Cross-Platform Retrieval of a Chronically Implanted Leadless Pacemaker Using a Dedicated Retrieval System.
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
backgroundLeadless pacemakers are increasingly used in patients in whom transvenous pacing leads are undesirable. However, management at battery depletion remains challenging, particularly for chronically implanted devices. CASE SUMMARY: A 74-year-old woman with prior bioprosthetic tricuspid valve replacement, atrial fibrillation, and complete atrioventricular block underwent leadless pacemaker implantation in 2019. At follow-up, device interrogation demonstrated battery depletion. A new leadless pacemaker was implanted via right femoral venous access. The chronically implanted device, located in the mid-right ventricular septum, was subsequently retrieved using a trilobed snare system. Engagement required multiple attempts because of difficulty achieving coaxial alignment; however, after capture, the device was recaptured and removed with minimal resistance and without arrhythmia, pacing instability, or complication.
conclusionThis case demonstrates the feasibility of cross-platform retrieval of a chronically implanted leadless pacemaker after prolonged dwell time in selected patients.
