We included all patients diagnosed with paroxysmal AF who underwent TELA at our institution between 04\/2011 and 06\/2017. TELA included pulmonary vein isolation, LA dome lesions and LA appendage exclusion. All (<jats:italic>n<\/jats:italic>\u2009=\u200955) patients received an implantable loop recorder (ILR), 30\u2009days post-operatively. Antiarrhythmic and anticoagulation therapy were discontinued at 90 and 180\u2009days postoperatively, respectively, if patients were free of AF recurrence. Failure was defined as \u2265two minutes of continuous AF, or atrial tachycardia.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>Fifty-five patients (78% males, mean age\u2009=\u200961.6\u2009years) qualified for the study. The average duration in AF was 3.64 +\/\u2212\u20093.4\u2009years, mean CHA2DS2-VASc Score was 2.0 +\/\u2212\u20091.6. The procedure was attempted in 57 patients and completed successfully in 55 (96.5%). Two patients experienced a minor pulmonary vein bleed that was managed conservatively. Post procedure, one patient experienced pulmonary edema, another experienced a pneumothorax requiring a chest tube and another experienced acute respiratory distress syndrome resulting in longer hospitalization. Otherwise, there were no major procedural complications. Success rates were 89.1% (<jats:italic>n<\/jats:italic>\u2009=\u200949\/55), 85.5% (<jats:italic>n<\/jats:italic>\u2009=\u200947\/55) and 76.9% (<jats:italic>n<\/jats:italic>\u2009=\u200940\/52) at 6, 12 and 24\u2009months, respectively. In the multivariate cox-proportional hazard model, survival at the mean of covariates was 86 and 74% at 12 and 24\u2009months, respectively.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Conclusion<\/jats:title>\n<jats:p>In this single center experience, TELA was a safe and efficacious procedure for patients with paroxysmal AF.<\/jats:p>\n<\/jats:sec>","DOI":"10.1186\/s13019-019-1018-4","type":"journal-article","created":{"date-parts":[[2019,11,6]],"date-time":"2019-11-06T18:03:19Z","timestamp":1573063399000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Safety and long-term efficacy of thoracoscopic Epicardial ablation in patients with paroxysmal atrial fibrillation: a retrospective study"],"prefix":"10.1186","volume":"14","author":[{"given":"John","family":"Johnkoski","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bryan","family":"Miles","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Sudbury","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammed","family":"Osman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhammad Bilal","family":"Munir","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sudarshan","family":"Balla","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9076-2321","authenticated-orcid":false,"given":"Mina M.","family":"Benjamin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2019,11,6]]},"reference":[{"key":"1018_CR1","doi-asserted-by":"crossref","unstructured":"Atrial fibrillation: current understandings and research imperatives.
