Abstract Funding Acknowledgements Type of funding sources: None. Background In patients with longstanding persistent atrial fibrillation (LSPAF), mapping with multipolar catheter can enhance identification of arrhythmogenic sources during ongoing AF/converted atrial tachycardia (AT), reduce procedure time, and improve outcome of catheter ablation. Purpose To compare procedural characteristics and long-term outcome of radiofrequency catheter ablation (RFA) for LSPAF between two mapping approaches in a prospective randomized bi-centric study. Methods Between 1/2019-9/2021, RFA was performed in in 172 patients with LSPAF. Mapping with multipolar catheter Pentaray (group 1, n=85) vs. mapping with ablation catheter Navistar STSF (group 2, n=87) were compared. Stepwise ablation to the desired AF termination included pulmonary vein isolation (PVI), electrogram guided left atrial (LA) ablation, CS isolation, and right atrial electrogram guided ablation. PVI, mitral isthmus, LA roof, and CTI block were Intermediate endpoints proved at the procedure end. Sinus rhythm (SR) restoration by ablation was the desired procedure endpoint. Follow-up included 7-day ECG monitoring every 3 months during the first year, and every 6 months afterwards. Results In groups 1 vs. 2, AF was terminated (into SR or AT) in 70 (82%) vs. 68 (78%) patients (p=0.81); and SR was restored by ablation in 54 (64%) vs. 46 (53%) patients(p=0.46), respectively. Procedure, fluoroscopy, and RF delivery times (min) were 251±46 vs. 257±45 (p=0.35); 10,4±2,8 vs. 11,0±3,1 (p=0.17), and 70±21 vs. 70±24 (p=0.98), respectively. At the end of 13-45 months follow-up, stable SR was present in 72 (85%) vs. 69 (79%), patients following repeat ablation in 42 (49%) vs. 42 (48%) patients. Only 29 (34%) vs. 26 (30%) patients remained free from any AF/AT recurrence (>30 s) after single ablation (all p=NS). Conclusion Mapping with multipolar catheter vs. standard ablation catheter was associated with nonsignificant differences in procedural characteristics and clinical results of RF catheter ablation for LSPAF.
