Evaluation of Two High-Power Ablation Approaches in the Management of Typical Atrial Flutter: A Retrospective Study.
Article in Annals of noninvasive electrocardiology : the official journal of the International Society for Holter and Noninvasive Electrocardiology, Inc, 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
objectiveTo compare the acute and long-term outcomes of high-power ablation for typical atrial flutter using a 4-mm irrigated catheter (4-IC) versus an 8-mm non-irrigated catheter (8-NIC).
methodsWe conducted a retrospective cohort study of 215 patients who underwent cavotricuspid isthmus (CTI) ablation between January 2019 and December 2024. Patients were divided into two groups based on the catheter used: 4-IC (n = 113) and 8-NIC (n = 102). Baseline, procedural, and follow-up data were analyzed.
resultsBoth groups achieved 100% acute procedural success with no significant difference in CTI block rates. The 8-NIC group had significantly shorter procedure duration (68.4 ± 15.2 vs. 77.4 ± 18.5 min, p < 0.001), reduced fluoroscopy time, and fewer lesions with shorter total RF delivery time. Periprocedural complications were rare and similar between groups. Over a mean follow-up of 15.7 ± 7.2 months, atrial flutter recurrence occurred in 12.6% of patients, with no significant difference between groups (14.2% vs. 10.8%, p = 0.442). Rates of atrial fibrillation, pacemaker implantation, and continued anticoagulation were also comparable.
conclusionBoth ablation strategies are safe and effective, with the 8-mm catheter offering greater procedural efficiency without compromising long-term outcomes.
