Esophageal Protection
Proactive cooling during radiofrequency (RF) cardiac ablation*
The ensoETM® system has been shown to reduce the risk of thermal injury through proactive cooling during RF cardiac ablation,1 as well as demonstrating a reduction in mean procedure time,3,4 increased mean lab throughput,5 and a 14% absolute increase in freedom from atrial arrhythmia at one year.6 Additionally, a real world retrospective study of 25,186 patients showed a statistically significant reduction in atrioesophageal fistula (AEF) from 0.146% with LET monitoring to 0% after adoption of the ensoETM® system.2

ensoETM®
FDA-granted indication to reduce the likelihood of ablation-related esophageal injury resulting from RF cardiac ablation procedures.1
Akin to a standard orogastric tube circulating chilled water, the ensoETM® system has been shown to reduce the risk of thermal injury through proactive cooling during RF cardiac ablation.1
