Percutaneous Removal of Left Atrial Appendage Occlusion Device With a Dedicated Retrieval System.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveSuccessful use of a novel percutaneous retrieval system (ŌNŌ retrieval system, ŌNŌCOR) to remove a significantly dislodged left atrial appendage occlusion device (Watchman FLX, Boston Scientific). KEY STEPS: First, a 17-F Bayliss VersaConnect and TruSteer catheter was advanced through a 20-F DrySeal sheath (Gore Medical). Then, the ŌNŌ retrieval system was advanced and positioned against the Watchman FLX device. Through this system, a 2.4-mm Raptor forceps (Steris) was advanced to grab one of the struts on the Watchman device. Slow traction on the Raptor forceps and simultaneous advancement of the ŌNŌ basket was performed to dislodge the Watchman device from the left atrial appendage. POTENTIAL PITFALLS: Device embolization, left atrial appendage avulsion, and pericardial effusion are some of the potential complications of the Watchman retrieval procedure. TAKE-HOME MESSAGE: Embolization of a left atrial appendage occlusion device is a rare but potentially devastating complication, and percutaneous retrieval with the ŌNŌ system may provide a safer alternative to surgical removal.
