Key result
Cryoballoon PVI for AF linked to esophageal thermal injury resolving after 7 days of treatment.
Why the study?
Esophageal injury after cryoballoon ablation is rare compared to radiofrequency ablation, but progression to atrioesophageal fistula can cause catastrophic iatrogenic outcomes.
Case Report (n=1)
Esophageal thermal injury is a rare but possible complication of cryoballoon ablation for atrial fibrillation, emphasizing the importance of esophageal protection.

Possible esophageal injury with cryoballoon AF ablation warrants caution; single case leaves incidence and prevention strategies open.
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.

Er-hong et al. (2024) conducted a case report in Symptomatic paroxysmal atrial fibrillation (n=1). Cryoballoon pulmonary vein isolation was evaluated on Esophageal thermal injury. Cryoballoon pulmonary vein isolation for atrial fibrillation can cause esophageal thermal injury, which resolved after 7 days of intervention in a 71-year-old female.
