Key result
Cryoballoon catheter ablation of non-pulmonary veins triggers is a novel and promising strategy for non-paroxysmal atrial fibrillation.
Why the study?
Non-paroxysmal AF involves triggers often found outside the pulmonary veins, motivating an overview of non-pulmonary vein triggers with a focus on cryoballoon catheter ablation.
Does cryoballoon catheter ablation of non-pulmonary veins triggers improve outcomes in patients with non-paroxysmal atrial fibrillation?
Does cryoballoon catheter ablation of non-pulmonary veins triggers improve outcomes in patients with non-paroxysmal atrial fibrillation?
Cryoballoon ablation targeting non-pulmonary vein triggers represents a promising strategy for managing non-paroxysmal atrial fibrillation.
May support cryoballoon ablation of non-PV triggers in non-paroxysmal AF; hypothesis-generating pending randomized trials.
INTRODUCTION: Catheter ablation has been demonstrated to be a safe and an effective treatment for drug resistant atrial fibrillation (AF); electrical isolation of pulmonary veins (PVI) is the main strategy in paroxysmal AF, since pulmonary vein triggers have a pivotal role in its pathogenesis; non-paroxysmal AF is a complex arrhythmia that results from the interplay of a substrate, namely AF-induced electrical and structural atrial remodeling, and a trigger that can be often found outside pulmonary veins, namely non-pulmonary veins triggers. AREAS COVERED: The aim of this review is to provide a state-of-the-art overview of non-pulmonary veins triggers with special focus on cryoballoon (CB) catheter ablation. EXPERT OPINION: Besides PVI, CB catheter ablation of non-pulmonary veins triggers is a novel and promising strategy for non-paroxysmal AF.
