Electrophysiological characteristics of pulmonary vein conduction recovery after radiofrequency ablation of atrial fibrillation.

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
This study aimed to identify the specific site of pulmonary vein conduction recovery after radiofrequency ablation (RFA) of atrial fibrillation (AF) for improved outcomes and reduced recurrence. Patients who underwent RFA for AF at our institution were included. The ablation procedure was guided by the ablation index (AI) and left, and right atrial pressures were monitored before and after ablation. Additionally, the recovery time of the sinoatrial node under Burst 400/300 ms stimulation was examined. Among 60 repeat procedure patients, 48 had paroxysmal and 12 had persistent AF. The recovery sites were 36.6% in the left anterior superior, 35% in the right anterior superior, 20% in the left anterior inferior, 20% in the right anterior inferior, 13.3% in the right top, and 11.6% in the left top. Preoperative and postoperative left and right atrial pressures were significantly higher in the persistent AF group compared with the paroxysmal AF group (P < 0.01). Postoperative left atrial pressures were significantly elevated compared to the preoperative levels in both groups (P < 0.01). Sinoatrial node recovery time in the persistent AF group was significantly longer compared with the paroxysmal AF group (P < 0.01). Under the guidance of AI, the recurrence of atrial fibrillation after radiofrequency surgery and the recovery of pulmonary vein potential are mostly concentrated in the upper anterior, lower anterior, and upper left and right pulmonary veins. As the duration of atrial fibrillation prolongs, the left and right atrial pressure increases year by year, while the recovery time of the sinus node gradually prolongs.
