Outcomes of surgical ablation for atrial fibrillation in on- versus off-pump coronary artery bypass grafting.

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
objectivesA considerable number of patients undergoing coronary artery bypass grafting surgery suffer from atrial fibrillation and should be treated concomitantly. This manuscript evaluates the impact of on-pump versus off-pump bypass grafting on the applied lesion set and rhythm outcome.
methodsBetween January 2017 and April 2020, patients who underwent combined bypass grafting and surgical ablation for atrial fibrillation were consecutively enrolled in the German CArdioSurgEry Atrial Fibrillation registry (CASE-AF, 17 centres). Data were prospectively collected. Follow-up was planned after one year.
resultsA total of 224 patients were enrolled. No differences in baseline characteristics were seen between on- and off-pump bypass grafting, especially not in type of atrial fibrillation and left atrial size. In the on-pump group (n = 171, 76%), pulmonary vein isolation and an extended left atrial lesion set were performed more often compared to off-pump bypass grafting (58% vs 26%, 33 vs 9%, respectively, P < 0.001). In off-pump bypass grafting a box isolating the atrial posterior wall was the dominant lesion (72% off-pump vs 42% on-pump, P < 0.001). Left atrial appendage management was comparable in on-pump versus off-pump bypass grafting (94% vs 91%, P = 0.37). Sinus rhythm at follow-up was confirmed in 61% in the on-pump group and in 65% in the off-pump group (P = 0.66). No differences were seen in in-hospital or follow-up complication-rates between the two groups.
conclusionsIn coronary artery bypass grafting patients undergoing concomitant atrial fibrillation ablation, our data suggests that the technique applied for myocardial revascularization (off-pump vs on-pump) leads to differences in the ablation lesion set, but not in safety and effectiveness.
