Safety of same-day discharge without anticoagulation for left-sided radiofrequency catheter ablations in pediatrics.

Background: For left-sided radiofrequency catheter ablation (LCA) in pediatrics, significant practice variability exists regarding anticoagulation and discharge practices. Given the lack of data in pediatric patients, the risks and benefits of these practices are not well defined.
Objective: The purpose of this study was to evaluate the safety of same-day discharge and use of aspirin (ASA) in pediatric patients following LCA.
Methods: We performed a retrospective cohort study of pediatric patients who underwent LCA from 2010 to 2020 at our institution. Discharge timing and ASA usage were based on operator preference. The primary outcome was incidence of postablation anticoagulation complications reported within 1 month of the procedure.
Results: Three hundred seventy-six patients underwent LCA and met inclusion criteria. Median [25th, 75th percentiles] age was 13.9 [10.5, 16.2] years; 18 (4.7%) had a history of structural heart disease. The most common substrates for ablation were Wolff-Parkinson-White syndrome (183 patients [48.7%]), concealed accessory pathway (159 patients [42.3%]), and ectopic atrial tachycardia (10 patients [2.7%]). Three hundred thirty-eight patients (89.9%) were discharged on the day of LCA. Seventy-six patients (20.2%) were prescribed ASA at discharge. Of those who underwent follow-up (273 patients [72.6%]), 7 (2.7%) reported an anticoagulation complication (5 with hematoma, 2 with headache). One of these patients was prescribed ASA; none required readmission. There was no correlation between anticoagulation complications and same-day discharge or with ASA usage.
Conclusion: Given the rare incidence of anticoagulation complications in pediatric patients undergoing LCAs, same-day discharge from the electrophysiology laboratory without anticoagulation should be considered.
