Failure of cilostazol in the prevention of ventricular fibrillation in a patient with Brugada syndrome.

abstract：BACKGROUND:Left atrial catheter ablation (LACA) has emerged as a successful method to eliminate atrial fibrillation (AF). Recent reports have described atrio-esophageal fistulas, often resulting in death, from this procedure. Temporary esophageal stenting is an established therapy for malignant esophageal disease. We d...
