Compares treatment options for Atrial Fibrillation Recurrent
Official title Pulsed Field Ablation Versus Conventional Radiofrequency Catheter Ablation for Repeat PVI in Patients With Paroxysmal AF
ClinicalTrials.gov ID: NCT06199180
What this study is testing
- What it's testing
- Various methods exist for performing pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF), including thermal ablation and pulse-field ablation (PFA). However, in cases requiring a second PVI for recurrent AF, radiofrequency ablation (RFA) is utilized in nearly 95% of instances post-acquiring a 3D high-density map from the left atrium (LA).
