A Prospective, Non-Randomized Study to Evaluate the CIRCA Esophageal Temperature Monitoring System in Prevention of Esophageal Lesions Following Atrial Fibrillation Radiofrequency Catheter Ablation

University of California, San Diego·interventional·Posted Jun 9, 2015·Updated Jun 2, 2021

In Brief

A clinical study evaluating Circa™ Probe for Atrial Fibrillation. Completed, enrolled 40 participants across 1 site.

Detailed Summary

The purpose of this study is to determine if the use of Circa™ temperature monitoring system during ablation procedures will reduce the risk of esophageal lesions or damage. Esophageal lesions caused by ablation could later develop into a potentially fatal atrio-esophageal fistula, which is hole between the upper chamber of the heart and the esophagus. Although development of atrio-esophageal fistula following atrial fibrillation ablation is extremely rare, the complication is severe and potentially life-threatening. Therefore, monitoring of esophageal temperatures has been adopted to prevent the development of esophageal lesions. The Circa™ temperature monitoring system allows cardiac electrophysiologists to monitor and thereby limit temperatures as well as duration of ablation in the esophagus throughout the procedure.

Interventions

Circa™ Probedevice

The Circa™ probe will be used to monitor esophageal temperature and guide ablation power and duration during the RFCA procedure. Following ablation esophagoscopy will be performed to assess for esophageal lesions.
