<p><strong>Aim.</strong> Endoscopic surgery demonstrates promising results of treatment in patients with non-paroxysmal atrial fibrillation. Minimally invasive thoracoscopic ablation contributes to the growing interest in such operations all over the world. Nowadays totally thoracoscopic ablations are available for patients in Russian Federation. Emphasis in our study was placed on the collection and analysis of data on thoracoscopic ablation procedures used for treating patients with lone

Data collection was based on emailed registration forms containing information about the date of procedures, type of ablation pattern, previous catheter procedures, used devices, methods of left atrial appendage closure and safety profile information. 30-day mortality, conversion to sternotomy/thoracotomy, stroke/ transient ischemic attack, reexplorations, cardiac tamponade and phrenic nerve damage were considered as major complications.</p><p><strong>Results</strong>. The study encompassed 10 cardiosurgical centers in Russian Federation where totally thoracoscopic ablations had been carried out between 2011– 2018. Six hundred fifty-two procedures were registered. Most patients were ablated in Dallas and Box Lesion patterns. Left atrial appendage exclusion was performed in 90,4% patients. Major complications were observed in 27 (4%) patients, mostly during the "learning curve" period.</p><p><strong>Conclusion.</strong> The given study is the first attempt to collect and systematize the data on a new surgical procedure for treatment of patients with atrial fibrillation. The data obtained allow for making a conclusion that thoracoscopic ablation is becoming a wide-spread surgical technique to treat patients with lone atrial fibrillation in Russia. The quantity of procedure increases annually. Introducing thoracoscopic procedures in clinical practice may be accompanied by complications at any center. Nevertheless, according to our investigation the rate of complications is low, which enables us to recommend thoracoscopic ablation to treat a numerous cohort of atrial fibrillation patients in Russia.</p><p>Received 13 June 2018.
