ABSTRACT
BACKGROUND:
Reflux-induced esophagitis might facilitate ablation-induced esophageal lesions (ELs) following pulmonary vein isolation (PVI), and these may progress to atrio-esophageal fistula (AEF). In contrast, preexisting ELs are not prone to progression but may affect procedure planning.OBJECTIVE:
To study the incidence of preexisting esophageal and upper gastrointestinal (UGI) pathology in patients undergoing PVI, and the relation to ablation-induced ELs.METHODS:
From 08/2018 to 09/2021, consecutive patients undergoing (radiofrequency [RF] or cryoballoon [CB]) PVI were examined by esophagogastroscopy (EGD) before and following ablation. Postprocedural endoscopic ultrasound (EUS) was added in 2021.RESULTS:
412 patients (median age 67.5 [IQR 61.3-75.0] years, 56.1% male) were studied. Preprocedural EGD showed abnormalities in 226/399 patients, 15% in the lower third of the esophagus. Half (99/226) were relevant for PVI, 13 procedures were postponed, 6 due to pathological EGD results. A third of the patients with new esophageal injury following ablation had preexisting esophagitis which was associated with a trend for a higher incidence of ELs after RF ablation (12.5 vs. 6.9%, p = 0.232), and a six- and two-fold higher rate of food retention after CB-PVI (28.6 vs. 4.5%, p = 0.008) and RF ablation (8.3 vs. 4.4%, p = 0.279), respectively.CONCLUSION:
(1) EGD before PVI showed UGI abnormalities in > 50% of patients, one-fourth of these relevant for PVI. (2) Esophageal inflammation was associated with a higher incidence of post-ablation (peri)-esophageal injury. Whether having this information before ablation is able to reduce ELs or AEF remains to be shown.Key words
