U.S., April 22 -- ClinicalTrials.gov registry received information related to the study (NCT07541989) titled 'Pulsed-Field Ablation With/Without Electrogram Mapping' on April 13.

Brief Summary: Pulsed field ablation (PFA) has demonstrated favorable safety and efficacy in atrial fibrillation ablation, particularly for pulmonary vein isolation (PVI). However, the optimal PFA-based ablation strategy for non-paroxysmal atrial fibrillation remains uncertain. In addition to anatomical lesion sets such as PVI and posterior wall isolation (PWI), Electrogram Mapping of Key Substrates may allow identification of residual arrhythmogenic areas that contribute to the maintenance of atrial fibrillation. In the investigators' previously completed single-...
