Conclusion
Although the esophageal injury after cryoballoon ablation is rare and
reversible, once progressed into AEF, it could be catastrophic. The
location between the esophagus and LIPV, the balloon temperature, the
freezing duration, LET,obesity can be considered as risk factors. Hence,
integral anatomic assessment should be performed, LET monitoring and
freezing time and temperature controlling as well as PPI prophylaxis
should be carefully deployed with regard for esophageal protection.
Furthermore, a high level of suspicion after ablation procedure is
necessary so that we could recognize and control the esophageal injury
before it is too late.
