Delayed Aortic Embolization of a Left Atrial Appendage Occlusion Device: Implications for Risk-Stratified Postprocedural Management.

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 an established alternative to long-term anticoagulation for stroke prevention in select patients with atrial fibrillation. Device embolization is rare, most commonly occurring intraprocedurally or within 24 hours. CASE SUMMARY: A 67-year-old man with paroxysmal atrial fibrillation underwent successful implantation of a Watchman FLX device. Eighteen days later, while shoveling snow, he developed sudden-onset chest and back pain followed by bilateral lower extremity paralysis. Computed tomography revealed complete mid-abdominal aortic occlusion from embolization of the LAAO device. Despite emergent endovascular retrieval and restoration of aortic flow, the patient developed fatal distributive shock from severe ischemia-reperfusion injury. DISCUSSION: This case illustrates a rare but clinically significant presentation of delayed device embolization. This patient possessed multiple National Cardiovascular Data Registry-identified risk factors for postdischarge device embolization, indicating that current risk stratification protocols may not be adequate for patients with device embolization risk factors. TAKE-HOME MESSAGES: Risk-stratified protocols with extended activity restrictions and earlier postprocedure surveillance imaging warrant investigation in patients with National Cardiovascular Data Registry-identified risk factors for postdischarge LAAO device embolization.
