Gastrointestinal Bleeding Caused by Atrioesophageal Fistula Secondary to Atrial Fibrillation Ablation

Abstract We present the case of a patient with upper gastrointestinal bleeding caused by an atrioesophageal fistula secondary to radiofrequency ablation for the treatment of refractory atrial fibrillation. Atrioesophageal fistula is a rare but serious complication. The endoscopic treatment is not established in the case of vascular-enteric fistulas and is still a challenge for endoscopists, which requires in most cases a multidisciplinary approach.
