Abstract
Introduction Catheter ablation (CA) is a treatment option for patients with atrial fibrillation (AF). However, interventional AF treatment has been associated with dangerous complications such as atrio‐esophageal fistula [1–3]. The [...]
: Background: Esophageal injury following catheter ablation of atrial fibrillation (AF) is reported to occur in 35% of patients. Even with a low energy setting (20–25 W), lesions develop in 10% of patients. Body mass index (BMI) has been reported to be a predictor of esophageal injury, indicating that patients with a low BMI ( Methods: Twenty patients with AF were included (age, 63±8 years; BMI, 22.9±1.3 kg/m[sup.2], left atrium diameter, 44±11 mm). If the esophageal temperature probe registered a temperature of >39 °C, radiofrequency (RF) application was stopped immediately. RF application could be performed in a “point by point” manner for a maximum of 20 s. Endoscopy was performed 1–5 days after ablation. Results: Esophageal mucosal injury was not observed in any patient in the study. Conclusions: Catheter ablation using ETM reduced the incidence of esophageal injuries, even in patients with a low BMI.
