Abstract Background/Objectives: Despite technological progress in atrial fibrillation (AF) ablation, vascular access complications remain common. Venous closure systems (VCS) may reduce these events and improve patient comfort, but data on their safety and e8icacy following cryoballoon-based pulmonary vein isolation (CB-PVI) are limited. This study assessed acute and long-term outcomes of VCS versus manual compression and figure-of-eight suture after CB-PVI. Methods: We conducted a prospective, single-center observational study comparing VCS with figure-of-eight suture plus manual compression post-CB-PVI. VCS patients were enrolled 09/2022 - 08/2023; controls were a 1:1 age-, sex-, and anticoagulation-matched cohort treated 01/2016 - 05/2021. Ultrasound-guided access was used in all VCS cases and routinely from 2018 in controls. Pressure bandage time was ≥60 minutes in VCS vs. ≥4 hours in controls. Vascular complications, emergency department (ED) visits, and readmissions were assessed over 12 months. Results: A total of 280 patients were included (mean age 70; 46.4% female; 38.9% paroxysmal AF). The VCS group had higher rates of hypertension (p=0.036), coronary disease (p=0.026), and BMI (p=0.006). Groin-related periprocedural complications were similar (22.9% vs. 22.1%, p=0.886); all were minor in the VCS group. One major complication occurred in controls. No groin-related ED visits occurred in the VCS group; one in controls. Thirty-day ED visits were lower with VCS (3.6% vs. 15.1%, p<0.001). Follow-up showed a trend
