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.

Conditions

Interventions

DEVICE

Circa™ Probe

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.
