Unraveling the Mysteries of Catheter Ablation for Atrial Fibrillation: From Clinical Observations to Mechanistic Explorations.

The author reflects on L. W. Lo and colleagues' paper that reports the results of patients, who underwent mapping and ablation techniques for atrial fibrillation (AF) and recurrence of AF. An overview of several papers that highlight the perplexities of catheter ablation for AF is offered. The author also comments on the underlying mechanisms of therapeutic ablation for AF.
