Increased Incidence of Esophageal Thermal Lesions Using the Second-Generation 28-mm Cryoballoon

Abstract

Using the second-generation 28-mm CB, ETLs were detected in 6 of 50 (12%) patients. All ETLs were in the healing process on repeat EGD. An esophageal temperature safety cutoff may prove valuable in the prevention of ETLs and requires further evaluation.
