This data sub-analysis of the German CArdioSurgEry Atrial Fibrillation Registry aims to describe the in-hospital and 1-year outcomes after concomitant surgical ablation, based on 2 different ablation approaches, epicardial and endocardial surgical ablation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS<\/jats:title>\n                  <jats:p>Between January 2017 and April 2020, 17 German cardiosurgical units enrolled 763 consecutive patients after concomitant surgical ablation. In the epicardial group, 413 patients (54.1%), 95.6% underwent radiofrequency ablation. In the endocardial group, 350 patients (45.9%), 97.7% underwent cryoablation. 61.5% of patients in the epicardial group and 49.4% of patients in the endocardial group presenting with paroxysmal atrial fibrillation. Pre-, intra- and post-operative data were gathered.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>Upon discharge, 32.3% (n\u2009=\u2009109) of patients after epicardial surgical ablation and 24.0% (n\u2009=\u200972) of patients after endocardial surgical ablation showed recurrence of atrial fibrillation. The in-hospital mortality rate was low, 2.2% (n\u2009=\u20099) in the epicardial and 2.9% (n\u2009=\u200910) in the endocardial group. The overall 1-year procedural success rate was 58.4% in the epicardial and 62.2% in the endocardial group, with significant symptom improvement in both groups. The 1-year mortality rate was 7.7% (n\u2009=\u200930) in epicardial and 5.0% (n\u2009=\u200917) in the endocardial group.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>Concomitant surgical ablation is safe and effective with significant improvement in patient symptoms and freedom from atrial fibrillation.
