Email: Magdalena.Rufa@rbk.de).  \nBackground: Coronary artery disease is the second leading cause of death across all age groups, while the prevalence of atrial fibrillation (AF) is increasing in the general population. This situation highlights the significant issue of concomitant surgical treatment for these two conditions. We aimed to investigate the safety and efficiency of pulmonary vein isolation (PVI) and left atrial appendage occlusion (LAAO) as concomitant procedures in patients undergoing off-vs. on-pump beating-heart coronary artery bypass  \ngrafting (CABG) at our centre.  \nMethods: This retrospective single-centre cohort included consecutive patients with AF who underwent CABG with concomitant epicardial PVI between December 2021 and November 2024 at Robert Bosch Hospital. Patients without preoperative AF, emergency cases, and those undergoing non-CABG concomitant procedures were excluded. Of 44 included patients, 27 had off-pump CABG (OPCAB) and 17 had onpump beating-heart CABG. Primary endpoints were sinus rhythm (SR) maintenance with or without antiarrhythmic drugs (AADs) and overall survival (OS); secondary endpoints were major adverse cardiac and cerebrovascular events (MACCE) and anticoagulation status at follow-up. Group comparisons used χ2 and  \nMann-Whitney U tests (two-sided, P\u003C0.05) .  \nResults: Follow-up was 100% at a median of 24 months. SR without AADs was observed in 77.7% of OPCAB and 64.7% of on-pump beating-heart patients; with AADs, rates were 81.4% and 70.5%, respectively. OS was in the OPCAB group 92%, respectively 94% in the on-pump beating-heart group. No strokes or myocardial infarctions occurred during follow-up; therefore MACCE-free, survival equalled OS.  \nOral anticoagulation was discontinued in 18.2% of patients, all in SR. No statistically significant between  \ngroup differences were detected for rhythm or survival outcomes.  \nConclusions: In patients with AF undergoing CABG, concomitant PVI yielded high SR maintenance and excellent mid-term survival in both off-pump and on-pump beating-heart settings, with no stroke or myocardial infarction observed at follow-up. These findings support the feasibility and safety of integrating  \nPVI into CABG—including OPCAB—for appropriately selected patients.  \nKeywords: Atrial fibrillation (AF); concomitant surgical ablation; pulmonary vein isolation (PVI); left atrial  \nappendage occlusion (LAAO); coronary artery bypass grafting (CABG)  \n^ ORCID: 0000-0003-0395-9834.  \n© AME Publishing Company.
