The ablation of persistent atrial fibrillation (AF) poses many challenges compared with ablation for paroxysmal AF, including greater procedural complexity, longer procedural time, unclear endpoints, increased patient comorbidity with a greater risk of procedural complications, and lower success rate. Nevertheless, using a combination of patient selection, careful procedural planning of both ablation strategy and endpoints, and by setting realistic patient expectations, successful ablation may be achieved. Further improvements will come from continued technical advances as well as from greater mechanistic understanding of persistent AF, including the physiologically-targeted ablation of localized rotors and focal sources that have recently been shown to maintain human AF.
