Colchicine to Prevent Atrial Fibrillation Recurrence After Catheter Ablation: A Randomized, Placebo-Controlled Trial

Circulation: Arrhythmia and Electrophysiology

Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:Inflammation may promote atrial fibrillation (AF) recurrence after catheter ablation. The first dose of the study drug was administered within 4 hours before ablation. 1.61];P=0.92) or at 3 months following ablation (14% versus 15%; HR, 0.95 [95% CI, 0.45–2.02];P=0.89).

Pulsed Field Ablation Using Focal Contact Force–Sensing Catheters for Treatment of Atrial Fibrillation: 1-Year Outcomes of the ECLIPSE AF Study

Circulation: Arrhythmia and Electrophysiology

Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:Pulsed field ablation (PFA) is a promising treatment for atrial fibrillation. There were no incidences of adverse event fistula, diaphragmatic paralysis, MI, pericarditis, thromboembolism, PV stenosis, transient ischemic attack, or death.
