Incidence and clinical relevance of upper gastrointestinal pathology during preprocedural endoscopy in patients undergoing pulmonary vein isolation.

(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.
