Résumé
Atrial fibrillation (AF) ablation is an increasingly utilized rhythm control strategy that can damage adjacent structures in the mediastinum including the esophagus. Atrioesophageal fistulas and esophagopericardial fistulas are life-threatening complications that are thought to progress from early esophageal mucosal injury (EI). Endoscopic ultrasound (EUS) has been proposed as a superior method than EGD to survey EI and damage to deeper structures. We aim to evaluate the safety of EUS in categorizing post-ablation EI and quantify EUS-detected lesions and their correlation with injury severity and clinical course. 234 consecutive patients between 2006-2020 who underwent AF ablation followed by EUS for the purpose of EI screening were retrospectively reviewed. Kansas City Classification (KCC) was used to classify EI (Type 1, Type 2a/b, Type 3a/b). EUS identified pleural effusions (31.6%) of patients, mediastinal adventitia changes (22.2%), mediastinal lymphadenopathy (14.1%), pulmonary vein changes (10.6%), and esophageal wall changes (7.7%). EGD revealed 175 (75%) patients without and 59 (25%) with EI. Patients with Type 2a/b EI and no EI were compared with multivariate logistic regression, and the presence of esophageal wall abnormality on EUS with OR 72.85 (95% CI 13.9-380.7), female sex with OR 3.97 (95% CI 1.3-12.3), and number of energy deliveries with OR 1.01 (95% CI 1.003-1.03), were associated with the presence EI type 2a or 2b. Pre-ablation PPI use was not associated with decreased risk of EI. EUS safely assesses mediastinal damage after ablation for atrial fibrillation and may excel over EGD in evaluating mucosal lesions of uncertain significance, with reduced risk of gas embolization in the setting of a full thickness injury (entero-vascular fistula). We propose an EUS-first guided approach to post-AF ablation examination, followed by EGD if it is safe to do so.

BACKGROUND & AIM
OBJECTIVE
Atrial fibrillation (AF) ablation is an increasingly utilized rhythm control strategy that can damage adjacent structures in the mediastinum including the esophagus. Atrioesophageal fistulas and esophagopericardial fistulas are life-threatening complications that are thought to progress from early esophageal mucosal injury (EI). Endoscopic ultrasound (EUS) has been proposed as a superior method than EGD to survey EI and damage to deeper structures. We aim to evaluate the safety of EUS in categorizing post-ablation EI and quantify EUS-detected lesions and their correlation with injury severity and clinical course.
METHODS
METHODS
234 consecutive patients between 2006-2020 who underwent AF ablation followed by EUS for the purpose of EI screening were retrospectively reviewed. Kansas City Classification (KCC) was used to classify EI (Type 1, Type 2a/b, Type 3a/b).
RESULTS
RESULTS
EUS identified pleural effusions (31.6%) of patients, mediastinal adventitia changes (22.2%), mediastinal lymphadenopathy (14.1%), pulmonary vein changes (10.6%), and esophageal wall changes (7.7%). EGD revealed 175 (75%) patients without and 59 (25%) with EI. Patients with Type 2a/b EI and no EI were compared with multivariate logistic regression, and the presence of esophageal wall abnormality on EUS with OR 72.85 (95% CI 13.9-380.7), female sex with OR 3.97 (95% CI 1.3-12.3), and number of energy deliveries with OR 1.01 (95% CI 1.003-1.03), were associated with the presence EI type 2a or 2b. Pre-ablation PPI use was not associated with decreased risk of EI.

CONCLUSIONS
EUS safely assesses mediastinal damage after ablation for atrial fibrillation and may excel over EGD in evaluating mucosal lesions of uncertain significance, with reduced risk of gas embolization in the setting of a full thickness injury (entero-vascular fistula). We propose an EUS-first guided approach to post-AF ablation examination, followed by EGD if it is safe to do so.
