Abstract
Atrial fibrillation (AF) is the most common sustained arrhythmia encountered in clinical practice. The contemporary management of AF is centered on symptomatic improvement, as well as reduction in the AF-associated morbidity and mortality. For many symptomatic patients catheter ablation offers an efficacious alternative to maintaining sinus rhythm when antiarrhythmic drugs have been ineffective, are contra-indicated, or cannot be tolerated. Over the past 15 years, catheter ablation has moved from an “experimental therapy” to the standard of care for the maintenance of sinus rhythm. The purpose of this review is to discuss the procedural refinements, and technological innovations proposed to improve the outcome of patients undergoing a percutaneous catheter ablation procedure for AF. This article focuses on a high-level review of the methods of a first procedure for catheter ablation of AF, as it is impossible to provide a detailed discussion of the nuances of each approach to AF ablation in a single review.
