Percutaneous Retrieval Strategies Following Left Atrial Appendage Occluder and Peri-Device Leak Closure Embolization.

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
backgroundPercutaneous LAAO is an established stroke-prevention strategy in atrial fibrillation patients unsuitable for long-term anticoagulation. Device embolization is uncommon but can cause severe complications requiring urgent intervention. ABSTRACT OF THE CASE: We report 2 related cases of device embolization associated with left atrial appendage occlusion and subsequent peri-device leak closure. The first involved early Amulet occluder embolization with mitral inflow obstruction and hemodynamic instability. The second occurred during peri-device leak closure after prior WATCHMAN implantation, when a 6 × 4-mm vascular occluder embolized upon release. In both cases, intraprocedural transesophageal echocardiography and fluoroscopy guided successful snare-based percutaneous retrieval with coaxial sheath-assisted extraction, avoiding surgery. Both devices were retrieved intact without major complications.
conclusionsPercutaneous retrieval of embolized LAAO devices is achievable with systematic planning and multidisciplinary preparedness. Growing LAAO volumes and leak reinterventions underscore the need for structured embolization rescue protocols.
