[A rare complication of cardiac radiofrequency catheter ablation: Esophageal irritation]. / Kardiyak radyofrekans kateter ablasyonunun nadir bir komplikasyonu: Özofagus irritasyonu.

ABSTRACT

The complication rate of radiofrequency catheter ablation varies depending on patient characteristics and treatment, and has been reported to be approximately 3%. Esophageal irritation is one significant complication of catheter ablation, and its most common result is atrio-esophageal fistulae. However, rarely, unexpected complications and clinical variants occur due to irritation of the vagal nerve or peri-esophageal tissue without fistula formation. In this case report, attention is drawn to this rare complication in two cases, one of which occurred after paraseptal-epicardial accessory pathway ablation, and the other after atrial fibrillation ablation. Both were symptomatic with severe gag reflex.
