Relationship between the posterior atrial wall and the esophagus: Esophageal position during atrial fibrillation ablation.

ABSTRACT:

Background

Atrial fibrillation ablation implies a risk of esophageal thermal injury. Esophageal position can be analyzed with imaging techniques, but evidence for esophageal mobility is inconsistent.

Objectives

The purpose of this study was to analyze esophageal position stability from one procedure to another and during a single procedure.

Methods

Esophageal position was compared in 2 patient groups. First, preprocedural multidetector computerized tomography (MDCT) of first pulmonary vein isolation and redo intervention (redo group) was segmented with ADAS 3D™ to compare the stability of the atrioesophageal isodistance prints. Second, 3 imaging modalities were compared for the same procedure (multimodality group): (1) preprocedural MDCT; (2) intraprocedural fluorosco
