Cardioesophageal fistulas (CEFs) are uncommon but life-threatening complications of radiofrequency (RF) catheter ablation of atrial fibrillation (AF). They are usually, but not exclusively, related to ablation of the left atrial posterior wall. We report a case of a 73-year-old man that presented with CEF following RF ablation in the coronary sinus, highlighting the importance of esophageal temperature monitoring whenever ablating in the posterior heart.
Keywords: atrial fibrillation; atrioesophageal fistula; catheter ablation; coronary sinus; esophagopericardial fistula.
