Prognostic Value of Spontaneous Potential in Left Atrial Posterior Wall Isolation and Radiofrequency Ablation for Non-Paroxysmal 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
Objective: This study aimed to examine the long-term effects of left atrial posterior wall spontaneous potential (SP) in patients with non-paroxysmal atrial fibrillation (AF) who underwent pulmonary vein isolation (PVI) combined with left atrial posterior wall isolation (PVI+BOX) ablation. Methods: Clinical data were retrospectively collected from 140 patients with symptomatic non-paroxysmal atrial fibrillation (NPAF) who underwent first-time radiofrequency ablation between 2022 and 2023. Based on the surgical procedure, patients were categorized into the pulmonary vein isolation group (PVI group) and the pulmonary vein isolation + left atrial posterior wall isolation group (PVI+BOX group). The PVI+BOX group was further subdivided into the spontaneous potential group (SP group) and the no-spontaneous potential group (no-SP group) based on the presence of SP after left atrial posterior wall isolation. Patients underwent monthly follow-ups in the clinic or via telephone and received 72-hour dynamic electrocardiography (ECG) at 3 and 12 months postoperatively. AF recurrence was compared among the groups, and factors associated with recurrence following AF ablation were analyzed. Results: The PVI+BOX group included 78 cases, with 45 in the no-SP group and 33 in the SP group, while the PVI group comprised 62 cases. No significant difference was observed in the postoperative recurrence-free rate between the PVI+BOX and PVI groups. However, the SP group exhibited a higher postoperative recurrence-free rate compared to both the no-SP group ( Conclusion: The presence of SP post-left atrial posterior wall isolation suggests a better long-term outcome in patients with NPAF following PVI+BOX catheter ablation.
