Does anatomic ganglionated plexi ablation improve the results of pulmonary vein isolation in patients with paroxysmal and persistent atrial fibrillation?
Ganglionated plexi ablation may be a safe and effective adjunct to pulmonary vein isolation for patients with paroxysmal and persistent atrial fibrillation.
The influence of the autonomic nervous system (ANS) on triggering and perpetuation of atrial fibrillation (AF) is well established. Ganglionated plexi (GP) ablation achieves autonomic denervation by affecting both the parasympathetic and sympathetic components of the ANS. GP ablation can be accomplished endocardially or epicardially, i.e. during the maze procedure or thoracoscopic approaches. Recent evidence indicates that anatomic GP ablation at relevant atrial sites appears to be safe and improves the results of pulmonary vein isolation in patients with paroxysmal and persistent AF.
