Real-World Experience with a New Vascular Closure Device in Electrophysiology Procedures with Large Bore Sheaths

Abstract 2338288, presented at Western Atrial Fibrillation Symposium 2026

Vascular closure devices offer proven benefits over manual compression for femoral venous access site management after electrophysiology procedures. The VASCADE MVP XL closure system is approved for sheaths up to 15Fr outer diameter (OD), however, its performance in procedures using large-bore sheaths (up to 17Fr OD) remains insufficiently evaluated. To evaluate the real-world outcomes in patients who received the VASCADE MVP XL device following large bore venous access electrophysiology procedures.This retrospective cohort study analyzed patients who received VASCADE MVP XL devices from 1/1/2024 to 10/30/2025 following atrial fibrillation (AF) pulsed field ablation (PFA), left atrial appendage closure (LAAC), or concomitant procedures. Primary outcomes included time to hemostasis (TTH), time to discharge (TTD), and same-day discharge (SDD) rates, stratified by gender and procedure type. Multivariable linear and logistic regression models assessed outcomes. Secondary outcomes were 30-day complication rates.A total of 1,623 patients (35.4% females, median age 71 years [IQR 63-77]) underwent procedures with VASCADE MVP XL closure during the study period. Procedure types included 73.9% AF PFA, 18.4% LAAC, and 7.6% concomitant procedures. Median TTH was 2 minutes (IQR 1-4), and median TTD was 3.5 hours (IQR 2.9-4.5). The SDD rate was 92.5%. After multivariable adjustment, no significant differences in TTH, TTD, or SDD were observed between gender and procedure types (all P>0.05). Thirty-day complications occurred in 20 (1.2%) patients. Complication rates differed by procedure types (p=0.016), with LAAC procedures showing higher rates (3.0%) compared to AF PFA (0.75%). No gender difference in complication rates was observed.These findings provide valuable real-world evidence supporting the safety and efficacy of the VASCADE MVP XL closure system in large-bore sheath procedures such as AF PFA, LAAC, or concomitant procedures.
