However, the comparative efficacy, safety, and procedural efficiency of the Sphere-9 lattice-tip catheter and the FARAPULSE pentaspline catheter have not been established in patients with persistent atrial fibrillation. Furthermore, outcomes following a pulmonary-vein-isolation-only strategy in this population have not been adequately evaluated using continuous rhythm monitoring.\n\nLANCE-AF is a prospective, multicenter, multinational, randomized, non-inferiority trial enrolling patients with symptomatic persistent atrial fibrillation. Eligible participants must have continuous atrial fibrillation lasting more than 7 but less than 365 days. Participants will be randomized in a 1:1 ratio to pulmonary vein isolation using either the Sphere-9 lattice-tip catheter or the FARAPULSE pentaspline catheter.\n\nAll participants will undergo pulmonary vein isolation as the sole permitted atrial fibrillation ablation lesion set. Empirical left atrial substrate modification will not be permitted. Participants presenting in atrial fibrillation or another non-sinus rhythm will undergo cardioversion to sinus rhythm before ablation. Acute procedural success will be confirmed by demonstration of entrance block in all treated pulmonary veins at the end of the procedure. Cavotricuspid isthmus ablation is the only permitted non-pulmonary-vein lesion set and may be performed only in participants with documented typical atrial flutter. Catheter use for cavotricuspid isthmus ablation will follow the treatment-group-specific requirements defined in the protocol.\n\nAn insertable cardiac rhythm monitor will be implanted during the index procedure and will provide continuous rhythm monitoring throughout the study, with a 2-month postablation blanking period.\n\nParticipants will be followed for 12 months after the index ablation procedure, with continuous rhythm monitoring provided by the insertable cardiac monitor. Scheduled remote assessments will be performed at 30 days, at the end of the 2-month blanking period, and at 6 months. An in-person assessment will be performed at 12 months. Unscheduled assessments will be performed as clinically indicated.\n\nThe primary endpoint combines acute ablation success with freedom from treatment failure through 12 months. Treatment failure is defined as the occurrence of any of the following: insertable-cardiac-monitor-documented atrial fibrillation, atrial flutter, or atrial tachycardia lasting at least 6 minutes; electrical or pharmacological cardioversion for an atrial arrhythmia; repeat atrial ablation; or protocol-defined use of a Class I or Class III antiarrhythmic drug. These events are assessed after the 2-month blanking period, except that any amiodarone use after the index ablation, including during the blanking period, constitutes treatment failure.\n\nSecondary outcomes include a composite of prespecified device- and procedure-related adverse events, postablation atrial fibrillation\u002Fatrial flutter\u002Fatrial tachycardia burden, the proportion of participants with an atrial arrhythmia burden below 0.1%, the duration of the longest atrial arrhythmia episode, time to first atrial arrhythmia episode, changes in quality of life assessed using the AFEQT and EQ-5D-5L questionnaires, total procedure time, left atrial dwell time, and fluoroscopy time and dose.\n\nAll insertable-cardiac-monitor-flagged episodes contributing to the efficacy endpoints will be reviewed by two independent adjudicators blinded to treatment assignment and catheter type. Disagreements will be referred to a third blinded adjudicator, with the majority determination considered final. Prespecified safety events will be reviewed by an independent Clinical Events Committee. An independent Data and Safety Monitoring Board will provide external safety oversight.

To aim for contiguous lesions, an inter-lesion distance of 5 mm should be argeted and tissue contact should be confirmed using impedence measures and real time monitoring of the temperature rise in the appropriate graph.\n\nIn patients with documented typical atrial flutter, cavotricuspid isthmus ablation will be performed with the Sphere-9 catheter using radiofrequency energy only.",[79],"Procedure: Pulmonary vein isolation",{"label":81,"type":6,"description":82,"interventionNames":83},"Farapulse","In the Farapulse arm, procedural guidance with three-dimensional electroanatomical mapping using OPAL HDx system with the FARAVIEW module is mandatory.
