Why the study?
Does catheter ablation of non-PV ectopy improve treatment efficacy in patients with paroxysmal atrial fibrillation initiated by non-pulmonary vein ectopy?
Does catheter ablation of non-PV ectopy improve treatment efficacy in patients with paroxysmal atrial fibrillation initiated by non-pulmonary vein ectopy?
Catheter ablation of non-pulmonary vein ectopy demonstrates moderate efficacy in treating paroxysmal atrial fibrillation initiated by these ectopic beats.
Answers are grounded in this paper and cite their sources.
May support non-PV ablation in select PAF; hypothesis-generating and leaves open need for randomized confirmation.
Ectopic beats initiating PAF can originate from the non-PV areas, and catheter ablation of the non-PV ectopy has a moderate efficacy in treatment of PAF.
