Esophageal perforation after radiofrequency ablation for atrial fibrillation.

A 69-year-old man underwent left atrial radiofrequency ablation for atrial fibrillation. After 10 minutes, the procedure was terminated due to pericardial tamponade secondary to perforation during mapping. Pericardiocentesis resolved the tamponade. Ablation was completed one week later, and the patient was discharged. Two days later, he presented with odynophagia. Computed tomography demonstrated small bilateral pleural effusions. He was judged to be stable and was discharged again, but returned 2 days later with chest pain. He was found to have esophageal perforation with empyema, which was repaired using a muscle patch and esophageal stenting, successfully treating the lesion with minimal morbidity.
