Epileptic Seizures from Atrio-Esophageal Fistula: A Deadly Outcome of Atrial Fibrillation Ablation.

Abstract

We report a case highlighting the global prevalence of atrial fibrillation (Afib) and the increased use of ablation therapy, underscoring the importance of understanding its complications, especially atrio-esophageal fistula (AEF), a rare but potentially fatal outcome. This case involves a 38-year-old male who underwent radiofrequency ablation for Afib and was subsequently hospitalized with abrupt left-sided weakness. Initially presumed to be a transient ischemic attack (TIA), his condition progressed to seizures and reduced consciousness. The computed tomography scans revealed pneumocranium, leading to a diagnosis of AEF. Despite the rapid identification of this complication, the patient's condition deteriorated quickly, resulting in his death on the 10th day. This case exemplifies that while AEF is an infrequent complication (0.1%-0.2%) following Afib ablation, it is of critical concern. The initial symptoms of AEF can be misleading, which accentuates the necessity for prompt recognition and timely intervention. Employing appropriate diagnostic techniques and ablation strategies are crucial to enhance patient outcomes and reduce the risks associated with AEF.
