Atrio-oesophageal fistula following circumferential pulmonary vein ablation: verification of diagnosis with multislice computed tomography

Abstract

A 37-year-old male patient with highly symptomatic and drug refractory paroxysmal atrial fibrillation underwent circumferential pulmonary vein ablation, using the electroanatomic mapping system (CARTO™, Biosense Webster Inc., Diamond Bar, CA, USA) and applying radiofrequency (RF) energy with an irrigated tip catheter (NaviStar™ ThermoCool®, Biosense Webster Inc.).
