- Data on prognostic implications of new-onset postoperative atrial fibrillation (POAF) after surgical aortic valve replacement (SAVR) is limited. We sought to explore associations between POAF, early-initiated oral anticoagulation (OAC), and long-term outcome after SAVR and combined SAVR+CABG.This is a retrospective, population-based study including all isolated SAVR (n=7038) and combined SAVR and CABG patients (n=3854) without a history of preoperative atrial fibrillation in Sweden 2007-2017. Individual patient data was merged from four nationwide registries. Inverse Probability of Treatment Weighting (IPTW) adjusted Cox regression models were employed separately in SAVR and SAVR+CABG patients. Median follow-up time was 4.7years (range 0-10years).POAF occurred in 44.5% and 50.7% of SAVR and SAVR+CABG patients, respectively. In SAVR patients, POAF was associated with increased long-term risk of death [adjusted hazard ratio (aHR) 1.21 (95% confidence interval 1.06-1.37)], ischaemic stroke [aHR 1.32 (1.08-1.59)], any thromboembolism, heart failure hospitalization, and recurrent atrial fibrillation. In SAVR+CABG, POAF was associated with death [aHR 1.31 (1.14-1.51)], recurrent atrial fibrillation, and heart failure, but not with ischaemic stroke [aHR 1.04 (0.84-1.29)] or thromboembolism. OAC was dispensed within 30days after discharge to 67.0% and 65.9% respectively of SAVR and SAVR+CABG patients with POAF. Early initiated OAC was not associated with reduced risk of death, ischaemic stroke or thromboembolism in any group of patients.POAF after SAVR is associated with an increased risk of long-term mortality and morbidity. Further studies are warranted to clarify the role of OAC in SAVR patients with POAF.
