Abstract— The esophageal
injury after cryoballoon ablation is much rarer than that after
radio-frequency ablation.Although it‘s rare, once progressed into
atrioesophageal fistula, it could cause a catastrophic iatrogenic
tragedy.We report on the occurrence of esophageal injury of A
71-year-old female with symptomatic paroxysmal AF who underwent
cryoballoon pulmonary vein isolation. The patient complaint about chest
pain exacerbated by swallowing on the postoperative day. Endoscopy
detected the esophageal thermal lesions. After 7 days of interventions,
the symptoms relieved and retest of endoscopy showed normal esophageal
mucosa.We suggest that esophageal protection in cryoballoon ablation is
just as important as in RF ablation.
