Purpose: To evaluate the effect of single-dose intravenous dexamethasone on atrial fibrillation (AF) recurrence following radiofrequency catheter ablation. Methods: A cohort of 84 adult patients (> 18 years) underwent catheter ablation at Mayo Clinic Rochester from January to March 2019. Only first-time ablation patients were included, with all re-do ablations excluded to minimize heterogeneity. Administration of intraoperative dexamethasone 4 mg or 8 mg was determined by chart review from the procedure. At our institution, intraoperative intravenous steroids are administered for postoperative nausea and vomiting (PONV) prophylaxis at the discretion of the anesthesiologist. AF recurrence was determined by ECG or cardiac monitoring within 3 months or between 3 and 12 months post-ablation with an in-person follow-up visit. Results: A total of 31 (36.9%) patients received intravenous dexamethasone compared to 54 (63.1%) who did not (approximating a 2:1 comparison group). The incidence of documented AF or atrial flutter, lasting greater than 30 s, within the first 3 months post-ablation was 29.0% in the dexamethasone group versus 24.5% in the non-dexamethasone group (p value 0.80). AF or atrial flutter recurrence at 3–12 months post-ablation was 3.2% in the dexamethasone group compared to 9.4% in the non-dexamethasone group (p value 0.41). Conclusion: These data suggest that intraoperative intravenous dexamethasone administered during AF ablation for postoperative nausea and vomiting prophylaxis may not have a significant effect on AF recurrence rates.
