Pericardial Tamponade After Left Atrial Appendage Occlusion Placement: A Case for Emergent Point-of-Care Ultrasound.
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
The prevalence of atrial fibrillation (AF) is rising, with left atrial appendage occlusion (LAAO) devices emerging as viable alternatives to anticoagulation for stroke prevention in high-risk patients. Although LAAO devices reduce bleeding risks compared to traditional anticoagulants, they carry procedural risks, including pericardial effusion and tamponade. We present a case of a 70-year-old male with a history of AF who presented to the emergency department with shortness of breath, dizziness, and weight gain five days post-LAAO placement. Point-of-care ultrasound (POCUS) revealed a large pericardial effusion with tamponade physiology. Emergency pericardiocentesis drained 800 mL of fluid, resulting in rapid clinical improvement. The patient's recovery was uneventful, and he was discharged two days later. Pericardial effusion and tamponade are serious complications of LAAO devices, often presenting with nonspecific symptoms. Emergency physicians should be familiar with the procedure itself, its complications, and the utility of POCUS in expediting care as seen in this case.
