The Amulet Device as Rescue Therapy in a Patient With Atrial Fibrillation and a Recurrent Gastrointestinal Bleed: A Case Report.
Article in Cureus, 2025. 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
In patients with non-valvular atrial fibrillation (AF) and a high stroke risk, long-term oral anticoagulation (OAC) is the standard of care. However, this becomes unfeasible in the presence of life-threatening bleeding, creating a significant therapeutic challenge. Percutaneous left atrial appendage occlusion (LAAO) offers a non-pharmacological alternative for stroke prevention. A 73-year-old female with persistent AF (CHA₂DS₂-VASc score of 6), end-stage renal disease on hemodialysis, and recurrent gastrointestinal (GI) bleeding was evaluated. Her GI workup suggested arteriovenous (AV) malformations of the small bowel. The patient's clinical course was complicated by recurrent hemorrhage despite a brief resumption of anticoagulant therapy, ultimately making long-term OAC an unsuitable strategy. She successfully underwent percutaneous LAAO with a 25 mm Amulet device (Abbott Medical, Chicago, IL, US). The procedure was uncomplicated, and she was discharged on a short course of dual antiplatelet therapy. This case demonstrates that the Amulet LAAO device is a safe and effective "rescue" strategy for stroke prophylaxis in patients with AF and an absolute contraindication to anticoagulation. It provides a definitive mechanical solution, resolving the critical conflict between thrombotic and hemorrhagic risks.
