Persistent Atrial Fibrillation Phenotypes and Ablation Outcomes: Persistent From Outset vs Progression From Paroxysmal AF.
Background: Many patients with persistent atrial fibrillation (PsAF) have progressed from an initial paroxysmal phenotype; however, there are patients in whom atrial fibrillation (AF) is persistent at diagnosis. Relatively little is known about this subgroup, but prior observational studies have suggested these patients have worse outcomes with ablation.
Objectives: This study sought to: 1) assess demographic and electrophysiologic characteristics of patients with PsAF at first diagnosis compared with those with who have progressed from paroxysmal atrial fibrillation (PAF); and 2) assess the impact of pattern of AF at diagnosis on recurrence post ablation.
Methods: CAPLA (Catheter Ablation for persistent atrial fibrillation: A Multicentre randomised trial of Pulmonary vein isolation [PVI] vs PVI with posterior Left Atrial wall isolation [PWI]) was a multicenter trial that randomized patients with PsAF to PVI plus PWI or PVI alone. Follow-up was 12 months. Outcomes were assessed after a 3-month blanking period.
Results: A total of 334 patients were included (median age 65.6 years, 23.1% female), 194 (58.1%) had PsAF at first AF diagnosis and 140 (41.9%) had PAF. Patients with PsAF at diagnosis were younger (age 64.0 vs 67.7 years, P = 0.005), had higher rates of heart failure (P < 0.001), and lower left ventricular ejection fraction (54.5% IQR: 40-60 vs 60% IQR: 50-61, P = 0.007). AF recurrence occurred in 85 (43.8%) with PsAF at diagnosis and 70 (50%) with PAF at diagnosis. PsAF at diagnosis was not associated with risk of recurrence on univariable (HR: 0.802; 95% CI: 0.585-1.101; P = 0.173) or multivariable analysis (HR: 0.922; 95% CI: 0.647-1.312; P = 0.650). Median AF burden was 0% in both groups (P = 0.125). There was no difference in left atrial size (P = 0.337) or bipolar voltage (P = 0.579) between the groups.
Conclusions: In the CAPLA cohort of patients, pattern of AF at first diagnosis did not influence post-ablation rate of AF recurrence or AF burden.

JACC: Clinical Electrophysiology is one of a family of specialist journals launched by the renowned Journal of the American College of Cardiology (JACC). It encompasses all aspects of the epidemiology, pathogenesis, diagnosis and treatment of cardiac arrhythmias. Submissions of original research and state-of-the-art reviews from cardiology, cardiovascular surgery, neurology, outcomes research, and related fields are encouraged. Experimental and preclinical work that directly relates to diagnostic or therapeutic interventions are also encouraged. In general, case reports will not be considered for publication.
