Atrial-oesophageal fistula

Atrio-oesophageal fistulas are rare pathological connections between the left atrium and the oesophagus

The presentation is non-specific. Patients may complain of fever, malaise, and/or dysphagia, or present with neurological symptoms 3

The chief cause of atrial-oesophageal fistulas is iatrogenic in the setting of cardiac ablation procedures, although, theoretically, many mediastinal pathology or procedure could potentially cause a fistula.

CT is the modality of choice and may reveal a communication between the left atrium and the oesophagus which can be evidenced by IV contrast present in the oesophagus.

Other possible features include:

The treatment is surgical, including resection and repair of the necrotic heart tissue and oesophageal resection of the fistulous area. Oesophageal stenting can be used as a temporizing measure. The mortality rate is high at ~60% (range 40-80%).
