Background: Colchicine is commonly used early after atrial fibrillation (AF) ablation to reduce inflammation and reduce AF recurrence, but there is limited long-term efficacy data.
Objective: To evaluate the effect of low dose colchicine use on long-term AF recurrence after AF ablation.
Methods: From 2013 to 2021, all AF ablations performed at a single tertiary care medical center were analyzed for colchicine use, clinical and procedural characteristics, and AF recurrence.
