Epicardial connection(s) inside the pulmonary vein antrum isolation lines contribute to subsequent atrial fibrillation: a case report.

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
Aims: Recent reports have demonstrated that ∼10% of patients with atrial fibrillation (AF) have epicardial connections (ECs) inside the pulmonary vein (PV) antrum isolation (AI) (PVAI) lines, which could be a possible mechanism of failure to achieve a complete PVAI, thus contributing to AF recurrence. Case summary: We present an 80-year-old female case with consistently continuing AF associated with ECs. Epicardial connections involving the PVs were detected in the left and right superior PVs after the completion of the PVAI. The AF steadily terminated after the ablation of those ECs. She has remained well without any AF or symptoms for 2 years post-ablation. Discussion: Those ECs might have played a possible important role in initiating and maintaining the AF. The mechanism(s) of the ECs may be a cornerstone of the failure to achieve a complete PVAI contributing to AF recurrence. Ablation of the EC(s) in addition to the PVAI may be better able to achieve the completion of the PVAI. Thus, physicians should be aware of the possibility of the presence of EC(s) when performing ablation of AF, even though complete PVAI lines have been achieved.
