High-Resolution Infrared Thermography of Esophageal Temperature During Radiofrequency Ablation of Atrial Fibrillation

Abstract

Infrared thermography provided dynamic, high-resolution mapping of esophageal temperatures during cardiac ablation. Esophageal thermal injury occurred with temperatures >50°C and was associated with large spatiotemporal gradients. Additional studies are warranted to determine the relationships between thermal parameters and esophageal injury.
