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.
Article Synopsis
- The study investigates the effect of the time from atrial fibrillation (AF) diagnosis to catheter ablation (DAT) on outcomes for patients with both AF and left ventricular systolic dysfunction (LVSD).
- Results show that a shorter DAT (less than 1 year) leads to better clinical outcomes, including higher rates of being free from arrhythmias and improved left ventricular ejection fraction (LVEF) after 12 months.
- The findings suggest that earlier catheter ablation in patients with AF and LVSD is linked to fewer hospitalizations and a better overall prognosis.
Background And Aims: Posterior wall isolation (PWI) is commonly incorporated into catheter ablation (CA) strategies for persistent atrial fibrillation (AF) in an attempt to improve outcomes. In the CAPLA randomized study, adjunctive PWI did not improve freedom from atrial arrhythmia at 12 months compared with pulmonary vein isolation (PVI) alone. Whether additional PWI reduces arrhythmia recurrence over the longer term remains unknown.

Article Synopsis
- A study was conducted to evaluate how the time from diagnosis to catheter ablation (DAT) affects the recurrence of atrial fibrillation (AF) in patients.
- The trial involved 334 patients divided into quartiles based on their DAT, with results showing varying AF recurrence rates; longer DAT generally correlated with higher recurrence.
- Despite this trend, overall quality of life improved significantly for all patients, indicating positive outcomes regardless of the length of the DAT, with only the longest DAT group showing a statistically significant risk of recurrence.
