Translations:Atrio-esophageal fistula/2/en

Posterior view of the position and relation of the esophagus in the cervical region and in the posterior mediastinum.

Layers of the GI track: the mucosa, submucosa, muscularis, and serosa.

Esophagus anatomy and nomenclature based on two systems.

CT showing anatomic relationship between an enlarged left atrium (LA) and esophagus (ESO): atrium abuts and indents into the anterior wall of the esophagus.

• Rare but deadly complication of atrial ablation
• There have been reported cases with various ablation modalities (including radiofrequency ablation, cryoablation, high intensity focused ultrasound, and surgical ablation)
• Incidence is low (<0.1%)
• Usually formed between esophagus and left atrium
• Thought to be related to adverse healing secondary to esophageal injury during the ablation procedure
