Percutaneous Retrieval of Embolized Left Atrial Appendage Occlusion Device From Mitral Valve Apparatus.
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
backgroundLeft atrial appendage occlusion (LAAO) is a safe and effective intervention for patients with atrial fibrillation who are unable to tolerate anticoagulation. Despite the safety of the procedure, complications including device displacement are a potential risk. CASE SUMMARY: A frail 84-year-old man underwent LAAO implantation, which was complicated by an early device displacement into the mitral apparatus, precipitating myocardial infarction and cardiogenic shock. The device was retrieved percutaneously with 2 snare wires, with a good patient recovery on follow-up. DISCUSSION: Device displacement to the mitral apparatus is a rare complication with high mortality. Transcatheter device retrieval is feasible with the right skills and equipment with good final results. TAKE-HOME MESSAGES: Early dislodgement of LAAO devices, though rare, can cause acute mitral valve obstruction and cardiogenic shock. Mechanical obstruction and ischemic events may coexist, necessitating rapid multimodality imaging and parallel management strategies.
