Percutaneous closure of residual leak after surgical left atrial appendage ligation: a case of stroke prevention in high-risk atrial fibrillation.
Article in BMC cardiovascular disorders, 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
Incomplete surgical left atrial appendage (LAA) closure is associated with increased thromboembolic risk in atrial fibrillation patients. We present a case of successful percutaneous closure of a significant residual leak following surgical LAA ligation. A 64-year-old female with atrial fibrillation (CHA₂DS₂-VASc score 4), prior surgical interventions including LAA ligation for thrombus formation, presented with ischemic stroke despite anticoagulation. Transesophageal echocardiography revealed a 10 mm residual communication following incomplete LAA closure. Percutaneous closure was performed using a 31 mm Amplatzer Amulet device with successful leak elimination. Percutaneous closure of residual leaks following incomplete surgical LAA closure represents a viable alternative to repeat surgery in high-risk patients. Individualized antithrombotic therapy is essential for optimal outcomes.
