Background: The mechanism of esophageal thermal injury (ETI; esophageal mucosal injury
and periesophageal nerve injury leading to gastric hypomotility) remains unknown when …

Introduction: Catheter ablation on the left atrial posterior wall has been reported to
potentially damage the esophagus or periesophageal vagal nerve. The aim of this study was …

Background—It is common practice to empirically limit the radiofrequency (RF) power when
ablating the posterior left atrium during atrial fibrillation ablation to avoid thermal injury to the …

Introduction: Atrioesophageal fistula is an uncommon but often lethal complication of atrial
fibrillation (AF) ablation. The purpose of our study was to prospectively investigate the …

TEE Probe and Esophageal Injury After AF Ablation Introduction The transesophageal echo
probe (TEE) is commonly used before and during atrial fibrillation (AF) ablation under …

Objectives This study sought to investigate the safety profile of a novel ablation index–
guided high-power short-duration (AI-HP) pulmonary vein isolation (PVI) in terms of …

Objectives: This study retrospectively evaluated the feasibility and esophageal thermal injury
(ETI) patterns of high-power short-duration (HPSD) radiofrequency atrial fibrillation (AF) …

Background The incidence of endoscopically detected esophageal lesions after pulmonary
vein isolation (PVI) is as high as 18%. Intraesophageal temperature rise (ITR) during …

Objectives: This study sought to determine the extent of lateral esophageal displacement
required during mechanical esophageal deviation (MED) and to eliminate luminal …

Esophageal injury is a rare but serious complication of catheter ablation for atrial fibrillation
using radiofrequency energy. Recent studies have begun to identify variables that may …
