Abstract

Since the advent of catheter ablation (CA) for atrial fibrillation (AF) in 1998, our understanding of the pathophysiology, as well as our capacity to target triggers and effectively achieve freedom from AF, has come a long way. However, as the average age of the population and the prevalence of chronic diseases increases, the progression of AF from paroxysmal (PAF) into persistent (PersAF) and long-standing persistent AF (LSPAF) is on the rise. Given the complex mechanisms involved and the presence of multiple trigger sites leading to recurrences, managing non-PAF is a challenge for electrophysiologists around the globe. Multiple ablation techniques have been investigated, some of which have shown promising results, but a standardized technique is yet to be elucidated. In this review, we outline the evidence behind contemporary ablation techniques in the treatment of AF.
