Optimal Surgical Approach to Left Atrioesophageal Fistula After Catheter Radiofrequency Ablation.

Atrioesophageal fistula formation is a rare but formidable complication after catheter radiofrequency ablation for atrial fibrillation. We present 4 patients who underwent urgent primary intracardiac repair of the left atrium via sternotomy with central cardiopulmonary bypass and early aortic cross-clamp, followed by repair of the esophagus. We believe that this approach represents the safest strategy for addressing this morbid and often fatal complication.
