Therefore, catheter ablation procedures, mainly the radiofrequency type, are widely used in its treatment. However, despite the efficacy of radiofrequency ablation, it has been associated with several complications, such as cardiac tamponade, embolic events, pulmonary vein stenosis, and extracardiac injuries., We hereby present a case of atrioesophageal fistula (AEF) complicating an AF ablation procedure that was first suspected on transthoracic echocardiography.
