    Abstract:
    Atrioesophageal fistula (AEF) is a rare but devastating complication of radiofrequency ablation (RFCA) for atrial fibrillation (AF) and is associated with high mortality rates. Whereas most cases of AEF are treated by emergency surgical interventions, we report a case of paroxysmal AF with AEF after combined therapy of catheter ablation and percutaneous left atrial appendage closure (LAAC), which was treated successfuly without major surgery or esophageal stenting. He was presented 18 days after the procedure, suffering chest pain, fever, and a transient loss of consciousness. Computed tomography (CT) of the chest disclosed a small accumulation of air in the region of the left atrium adjacent to the esophagus, suggesting AEF. Supported by early aggressive antibiotic therapy, pericardial drainage and a fasting state with adequate parenteral nutrition, resulted in improvement of his condition with no recurrence of symptoms. Subsequent chest CT scans confirmed disappearance of the leaked air and the patient was discharged home 28 days after admission with no neurological compromise. Early detection, rapid treatment and constant awareness of potential fatal consequences are prerequisites for successful treatment of this complication and prevention of fatal outcome.
