Esophageal Protection Study: A Multicenter Study

Esophageal cooling during AF ablation: The ensoETM probe is inserted via the orogastric route when the patient is under general anesthesia. The device is set to cool during ablation of the posterior aspect of the left atrium, to protect against transmitted thermal energy and so reduce or prevent esophageal thermal injury.

An esophageal temperature monitoring probe is a typical monitoring device used in standard of care AF ablations. This allows any temperature rise in the esophagus to be detected during ablation. If the temperature reaches \>38 degrees then it is widely recognized that ablation should be halted until the temperatures fall back to below 38 degrees. It therefore has the ability to detect esophageal temperature rise only.
