Atrioesophageal Fistula During Cryoballoon Ablation

To date, there is 1 case report publication of AE fistula during the employment of the first-generation cryoballoon (Gen-1). Recently the Arctic Front Advance system (second-generation cryoballoon) was introduced into the US and EU markets. For the purpose of peer education, we report a case of AE fistula that occurred during the utilization of the second-generation cryoballoon (Gen-2). Additionally, we review current best practices that may reduce the risk of AE fistula during any AF ablation procedure.
