Current Safety of Pulmonary Vein Isolation in Paroxysmal Atrial Fibrillation: First Experience of Same Day Discharge.

Introduction: Pulmonary vein isolation (PVI) has become the standard treatment of symptomatic atrial fibrillation. Patients remain hospitalized for at least 24 hours to detect potential complications in most centers worldwide. There is still a lack of data about the safety of same-day discharge.

Objectives: The aim was to compare the safety of same-day discharge with next day discharge after overnight monitoring.The rate of new hospitalization and visits to the emergency department and the costeffectiveness of the same-day discharge approach were evaluated.

Methods: We conducted a longitudinal and prospective cohort study of all the consecutive patients undergoing scheduled pulmonary vein ablation of either paroxysmal or persistent atrial fibrillation (AF). The complications were recorded by type and time of occurrence.

Results: Overall 58 patients were discharged within the same day and 137 patients stayed overnight after PVI. There were no significant differences in demography, comorbidities and other predictors of complications. No complications were reported after the sixth hour. We observed a significant difference in the number of visits to emergency department: 15.5% for the same-day discharge group vs. 30.7% for the overnight hospitalization group (p 0.03). Only 50% of the reasons to visit the emergency department were cardiovascular causes. No cases of pericardial tamponade were reported and none of the patients required new hospitalization up to 30 days of follow up.

Conclusions: Same-day discharge after PVI is feasible and cost-effective. This is the first study analyzing the experience in patients undergoing AVP,considering acare based component to this procedure. This approach would provide significant benefits for patients and health care providers.
