We describe the case of a 61-year-old man with a fatal atrioesophageal fistula following radiofrequency ablation (RFA) for paroxysmal atrial fibrillation (PAF). Esophageal injury was first noted on computed tomography (CT) scan 10 days following RFA. Fistulization occurred 41 days following the procedure.
