Stepwise logistic regression analysis identified age and APT as covariates correlated with bleeding. There was a trend toward increased bleeding risk in elderly patients receiving vs not receiving concomitant APT. CONCLUSION In ENSURE-AF, thromboembolic events were rare and absolute bleeding event rates were higher with concomitant APT. These findings may be relevant for AF-patients considered for dual therapy; even for a short treatment duration of 1 month.BACKGROUND Interventional left atrial appendage closure (LAAC) effectively prevents thromboembolic events in atrial fibrillation patients. Impaired left ventricular ejection fraction (LVEF) increases not only the thromboembolic risk but also the complication rates of cardiac interventions. The LAAC procedure's benefit in patients with an impaired LVEF, therefore, has yet to be investigated. METHODS LAARGE is a prospective, non-randomized registry depicting the clinical reality of LAAC in Germany. Procedure was conducted with different standard commercial devices, and follow-up period was one year. In the sense of an as-treated analysis, patients with started procedure and documented LVEF were selected from the whole database. RESULTS 619 patients from 37 centers were categorized into one of three groups LVEF > 55% (56%), 36-55% (36%), and ≤ 35% (8%). Prevalence of cardiovascular comorbidity increased with LVEF reduction (p  less then  0.001 for trend). CHA2DS2-VASc score was 4.3, 4.8, and 5.1 (p  less then  0.001), and HAS-BLED score was 3.7, 4.1, and 4.2 (p  less then  0.001). Implantation success was consistently high (97.9%), rates of intra-hospital MACCE (0.5%), and other major complications (4.2%) were low (each p = NS). Kaplan-Meier estimation
