Left Atrial Electrophysiological Properties after Pulmonary Vein Isolation Predict the Recurrence of Atrial Fibrillation: A Cohort Study.

ABSTRACT:

Background

The aim of this work was to investigate left atrial electrophysiological properties for their ability to predict the recurrence of atrial fibrillation (AF) following pulmonary vein isolation (PVI).

Methods

The study comprised 53 patients with AF [62 (interquartile range (IQR): 52-68) years old; 47.2% females]. High-density, three-dimensional electro-anatomic mapping using PentaRay was conducted during sinus rhythm in the left atrium (LA) immediately after PVI. LA conduction time, conduction velocity in predefined anterior and posterior routes, low voltage area percentage and distribution were assessed.

Results

The AF recurrence group had longer LA conduction time compared to the non-recurrence group [11 (IQR: 10-12) ms vs. 9 (IQR: 8-10) ms, p = 0.001
