Comparison of Two High-Power Ablation Strategies for Typical Atrial Flutter: Acute and Long-Term Outcome.
Article in Annals of noninvasive electrocardiology : the official journal of the International Society for Holter and Noninvasive Electrocardiology, Inc, 2025. 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
backgroundAblation of the cavo-tricuspid isthmus (CTI) is the standard treatment for typical atrial flutter. High-power strategies have been described to improve lesion efficacy and durability.
objectiveTo compare the acute success, safety, and long-term outcomes of two strategies of high-power CTI ablation using 8-mm gold-tip nonirrigated and 4-mm irrigated-tip catheters.
methodsThis single-center prospective cohort study included 253 patients who underwent CTI ablation. Patients were treated with either an 8-mm gold-tip nonirrigated catheter (60 W, ≥ 30 s) or a 4-mm irrigated catheter (45 W, ≥ 30 s). Procedural outcomes, safety, and long-term follow-up data were assessed.
resultsUsing a propensity score matching, 180 patients were yielded with a 1:1 ratio. Acute bidirectional CTI block was achieved in 97.8% of the 4-mm group and 97.8% of the 8-mm group (p = 1.000). No major complications were reported. During a median follow-up of 27.7 ± 20.1 months, freedom from atrial arrhythmia was 93.3% in both groups (log rank p value 0.935). No significant differences were observed in atrial fibrillation incidence, pacemaker implantation, or cardiovascular mortality between the groups.
conclusionHigh-power CTI ablation with both 8-mm gold-tip nonirrigated and 4-mm irrigated catheters is highly effective and safe, providing durable outcomes over long-term follow-up.
