Long-term outcome following successful catheter ablation of atrial tachycardia originating from the pulmonary veins: Absence of late atrial fibrillation

Abstract

Atrial Fibrillation and Pulmonary Vein Tachycardia. Objectives: This study aimed to characterize the long-term outcome and incidence of atrial fibrillation (AF) in patients following catheter ablation of focal atrial tachycardia (AT) from the pulmonary veins (PV). Background: Although both AT and AF may originate from ectopic foci within PVs, it is unknown whether PV AT patients subsequently develop AF. Methods: Twenty-eight patients with 29 PV ATs (14%) from a consecutive series of 194 patients who underwent RFA for focal AT were included. Patients with concomitant AF prior to the index procedure were excluded. Results: The minimum follow-up duration was 4 years; mean age 38 ± 18 years with..
