Comparative Outcomes of Deep Sedation Versus General Anesthesia in Cryoablation for Atrial Fibrillation: Insights From the Korean Heart Rhythm Society Cryoablation Registry.
Article in Korean circulation journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
objectivesThe optimal sedation strategy for cryoablation in atrial fibrillation (AF) remains uncertain. We aimed to compare the safety and efficacy outcomes between deep sedation (DS) and general anesthesia (GA) in patients undergoing cryoablation.
methodsWe analyzed 2,068 patients from the Korean Heart Rhythm Society Cryoablation Registry who underwent cryoablation for AF between 2018 and 2022. Patients were grouped based on anesthesia method: DS (n=1,390) and GA (n=678). Propensity score matching (1:1) was performed to adjust for baseline differences. The primary outcomes included any recurrence of atrial tachyarrhythmias (ATs) after a 3 month blanking period and procedure-related major complications.
resultsThe study included 2,068 patients (average age: 61.7±9.7 years; 76.3% male; 57.9% with persistent AF). In the matched cohort, AT recurrence rates were comparable between DS and GA groups (47.1% [n=220] vs. 53.1% [n=225]; p=0.99) during a mean follow-up of 1.2 years. The incidence of major complications was also similar between groups both before (2.8% [n=39] vs. 2.4% [n=16]; p=0.66) and after matching (2.3% [n=15] vs. 2.1% [n=14]; p=1.00). Subgroup analysis based on body mass index (≥30 vs. <30) revealed no significant differences in efficacy and safety outcomes between the DS and GA groups.
conclusionsDS provides a comparable safety and efficacy profile to GA for cryoablation in patients with AF. These findings support the use of DS as a feasible and practical alternative to GA in routine clinical practice.
