Retrieval Strategies for Embolized Left Atrial Appendage Closure Devices.
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
backgroundDevice embolization (DE) is a rare but potentially life-threatening complication of left atrial appendage occlusion (LAAO). As landmark trials broaden the eligible population for LAAO, operator preparedness for DE management becomes increasingly critical. CASE SUMMARY: We present 4 cases of LAAO DE managed with distinct retrieval strategies: 1) open surgical retrieval with concurrent AtriClip ligation for an endothelialized left atrial device; 2) sequential transseptal then retrograde arterial snaring for intraprocedural migration to the abdominal aorta; 3) transseptal retrieval using a dedicated ONO system with cerebral embolic protection for partial left atrial dislodgment; and 4) retrograde large-bore arterial retrieval for delayed aortic embolization.
conclusionsPercutaneous retrieval is feasible in most cases when tailored to embolization location. Surgical backup remains indispensable. Prevention requires rigorous preprocedural imaging, accurate sizing, and routine postimplant surveillance. TAKE HOME MESSAGE: LAAO embolization has high mortality, accurate device sizing as well as follow up imaging in paramount.
