Authors' conclusion

Following AF ablation, the use of a VCS results in a significantly shorter time to ambulation, time to haemostasis, and time to discharge eligibility.

Study context

Population: Patients undergoing single-shot pulmonary vein isolation (PVI) for AF
Participants: 125 patients

Comparison: Venous closure system vs figure-of-eight suture and manual compression
Primary endpoint: Efficacy: time to ambulation; safety: major periprocedural adverse events
Follow-up: Until hospital discharge (safety)
