Long-Term Outcomes of Concomitant Left-Sided Cryoablation During Totally Endoscopic Mitral Valve Surgery.
Article in Interdisciplinary cardiovascular and thoracic surgery, 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
objectivesConcomitant atrial fibrillation ablation is a well-established procedure in patients undergoing mitral valve (MV) surgery. However, data concerning the long-term outcomes of cryoablation performed during totally endoscopic MV surgery remain limited. Furthermore, different lesion sets and energy sources used in endoscopic approach may result in varying outcomes. We therefore, analysed rhythm outcome in patients undergoing left-sided cryoablation during totally endoscopic MV surgery.
methodsPatients, who underwent totally endoscopic MV surgery with concomitant left-sided cryoablation between 2016 and 2023 at our centre were included in the study. The retrospective data analysis was based on 24-h Holter monitor follow-up data.
resultsA total of 123 patients were included in the study. No complications related to the ablation procedure were observed. The median follow-up period was 36.0 (interquartile range: 17-60) months. During this period, 34 episodes of atrial fibrillation recurrence were documented, corresponding to a recurrence rate of 8.43 per 100 patient-years (95% confidence interval: 5.90-11.73). The estimated freedom from AF at 1, 3, and 5 years were 96.6%, 86.3%, and 69.4% respectively. Type of atrial fibrillation (P = .004; hazard ratio [HR]: 2.521; 95% confidence interval [CI]: 1.347-4.716) and left atrial volume (P = .003; HR: 1.010; 95% CI: 1.003-1.016) were identified as predictors for atrial fibrillation recurrence.
conclusionsConcomitant left-sided cryoablation during totally endoscopic MV surgery is a safe and effective procedure for atrial fibrillation treatment. The encouraging long-term outcomes support the consideration of this approach in totally endoscopic mitral surgery.
