Esophageal injury, perforation, and fistula formation following atrial fibrillation ablation.

Esophageal perforation and fistula formation following atrial fibrillation ablation are rare complications with poor prognosis. Various strategies have been proposed to protect the esophagus and reduce the incidence of this fearful complication. Pulsed field ablation is a promising new ablation technology that may be the future answer toward reducing the incidence of esophageal complications. The recognition of risk factors and preventative strategies of esophageal injury, perforation, and fistula formation following atrial fibrillation ablation is essential to reduce the incidence of this dreaded complication (online abstract figure).
