Successful management of an atrio-esophageal fistula after atrial fibrillation ablation: a case report

Abstract Background Atrio-esophageal fistula is a rare but still a catastrophic complication of radiofrequency ablation of atrial fibrillation. We report a successful case of atrio-esophageal fistula with right posterolateral thoracotomy and right femoral cannulation of cardiopulmonary bypass. Case presentation A 67-year-old man underwent radiofrequency ablation for atrial fibrillation. Nineteen days later, he developed cerebral infarction, and computed tomography showed air in the left atrium. He was transferred to our hospital for surgery. The upper body was placed in the left lateral decubitus position, and the lower body was placed in the left hemilateral decubitus position. The surgical approach was a right posterolateral thoracotomy in the 5th intercostal space. At first, the esophagus was transected at the diaphragm and tracheal carina levels. Then, an arterial line was inserted into the right common femoral artery and venous line into the right common femoral vein. Three U-shaped sutures of 3-0 polypropylene were placed to stop bleeding from the atrium. The esophagus was removed while snaring the 3-0 polypropylene sutures. There were two holes in the esophagus. Four drains were placed to clean the repaired site. After chest closure, the patient was placed supine. Cervical esophagostomy and enterostomy were performed. Gastric tube reconstruction via the retrosternal route was performed on postoperative day 28, and the patient was transferred to another hospital for rehabilitation on postoperative day 99. Conclusions It is important to thoroughly discuss with esophageal surgeon how to reach the heart and esophagus, and how to reconstruct the esophagus later.
