Very high-power and short-duration radiofrequency ablation for atrial fibrillation in a Latin American low-volume private center.

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
backgroundCenter volume and operator experience/training are important factors impacting outcomes in AFib CA. Setting for RF delivery (power, duration, and contact force) associated with better outcomes remains to be determined.
methodsThis is an observational, longitudinal, and retrospective study. All consecutive procedures performed between December 12, 2013, and March 9, 2023, in a low-volume private center in Latin America were analyzed. Procedure characteristics and outcomes were compared between STD and vHPSD.
resultsTwo hundred ten procedures were performed on 194 patients. Median annual number of procedures was 19 (7-29). Median age was 62 (52-68), and majority were male (71%). Median procedure duration was 155 (125-195) min, mean fluoroscopy time 32.8 ± 15 min and mean fluoroscopy dose 373.5 ± 208.9 mGray. Median follow-up was 27 months, significantly longer in STD compared with vHPSD group (43 [31-68] vs. 13 [8-19], respectively; P ≤ 0.001). The recurrence rate was 33.2% and major complications 8.6%. Compared with STD, vHPSD resulted in a significantly shorter procedure duration (125 vs. 180 min, P ≤ 0.001), shorter fluoroscopy time (22.7 ± 9.5 vs. 39.2 ± 14.3 min, P ≤ 0.001), and lower fluoroscopy dose (283.8 ± 161.1 vs. 438.3 ± 216.1 mGray, P ≤ 0.001). No long-term recurrence difference was observed when the follow-up periods were comparable. No difference in complication rate was observed (8.5% vs. 8.6%, P = 0.988).
conclusionsOutcomes in AFib CA in a Latin American low-volume private center can be considered acceptable, with efficacy and safety similar to those reported in the literature. Compared with STD ablation, vHPSD showed higher efficiency with similar efficacy and safety.
