Left atrial appendage closure with clip in patients undergoing off-pump coronary artery bypass grafting.
Article in Journal of cardiothoracic surgery, 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
backgroundWe sought to investigate the safety of using left atrial appendage (LAA) closure with clip devices in patients who underwent off-pump coronary artery bypass grafting and who experienced atrial fibrillation.
methodsWe applied LAA clips in 25 patients between November 2018 and May 2025. The mean age was 74 years, and 5 patients were female. All patients underwent off-pump CABG via a heart positioner and stabilizer and an LAA clip (21 with AtriClip and 4 Penditure). The mean number of coronary anastomoses was 4.0. The mean follow-up period was 28.6 ± 17.5 months.
resultsThere were no complications related to the LAA clips. During the operations, we used a fluorescence imaging system in 13 patients to confirm the closure of the LAA. Moreover, in all 25 patients, postoperative enhanced computed tomography confirmed the occlusion of the LAA. No patient experienced stroke or thromboembolic events during the follow-up period.
conclusionsLeft atrial appendage closure with a clip was safely performed in patients undergoing off-pump CABG without harmful effects on the heart or grafts. This surgical option may be effective for stroke prevention in patients undergoing off-pump CABG.
