Abstract

Background: Pulmonary vein (PV) reconnection is the Achilles heel of pulmonary vein isolation (PVI) for atrial fibrillation (AF). Dissociated pulmonary vein potentials (dPVP) may reflect abnormal PV automaticity, indicate more extensive PV muscular sleeve or may simply be an epiphenomenon. Objective: This study sought to determine the incidence, characteristics and prognostic significance of dPVP following PVI for AF. Methods: 89 consecutive patients (mean age 58.2±8.4 years, 75% male, 74% paroxysmal, 26% persistent AF) underwent antral PVI using threedimensional mapping systems with image integration with the endpoint of bidirectional PV block. Following PV electrical isolation the presence..
