Combined management of esophagopericardial fistula sustained after catheter ablation for atrial fibrillation

INTRODUCTION: Radiofrequency ablation (RFA) is an effective treatment modality for atrial fibrillation (AF); however, serious complications can occur. We present the case of a highly morbid consequence, the esophagopericardial fistula (EPF). CASE: A hemodynamically unstable patient with a history of AF and recent RFA presented with chest pain and was found to have pneumopericardium and pericardial effusion. The patient went to the operating room emergently for combined management with surgical pericardial window and endoscopic stent placement. CONCLUSION: EPF must be on the differential diagnosis while evaluating patients who develop constitutional symptoms or sudden onset chest pain days or weeks after catheter ablation for AF. Early detection followed by aggressive management with a combined surgical and endoscopic approach may be considered for successful treatment of this type of postablation esophageal perforation if an atrioesophageal fistula is effectively ruled out.
