Thoracoscopic Pulmonary Vein and Left Atrial Posterior Wall Isolation Combined with Left Atrial Appendage Resection in Patients with Long-Standing Persistent 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
objectiveTo evaluate the efficacy and safety of a modified technique for totally thoracoscopic left atrial posterior wall and pulmonary vein isolation in patients with long-standing persistent atrial fibrillation.
methodsFrom April 2017 to December 2018, we included in this study 28 consecutive patients who underwent thoracoscopic left atrial posterior wall and pulmonary vein radiofrequency isolation combined with left atrial appendage resection. We used a device with irrigated electrodes (Medtronic Cardioblate Gemini-s). The original surgical technique "GALAXY" proposed by Doty in 2012 was modified. The number of ablations was significantly increased, and frequent position changing of the ablation device and change of device angulation were added.
resultsSinus rhythm was restored in all patients. There was no operative mortality, no myocardial infarction, and no stroke or transient ischemic attack. One patient required sternotomy and another survived left anterolateral thoracotomy due to bleeding. A 180-day follow-up (24-hour Holter monitoring) revealed no sign of recurrence of atrial fibrillation or other supraventricular arrhythmia in any patient. Mean follow-up was nine months (range: 6-16 months). At the last follow-up, 26 patients (92,9%) were in sinus rhythm (24-hour Holter monitoring).
conclusionA frequent ablation device position changing during the surgery makes it possible to achieve complete left atrial posterior wall and pulmonary veins isolation. An increased number of applications allows to avoid a false positive transmural damage assessment showed by impedance drop. Also, frequent position changing of the ablation device and increased number of applications do not affect the number of postoperative complications.
