Dr Scanavacca et. al., Incor Group, Brazil
They conducted a randomized trial to assess different methods of esophageal temperature monitoring and follow up with endoscopy. Quick summary:
- 20 patients in each of three arms of the trial: No Temperature Probe, Single-sensor Temperature Probe, and CIRCA.
- 25% of patients in the group with no temperature probe (20W on posterior wall) had esophageal lesions post procedure.
- 30% of the patients in the single-sensor group (37.5C cutoff, 30W until temperature cut-off reach then 20W) had esophageal lesions.
- ZERO PERCENT, 0%, of the patients in the CIRCA group (37.5C cutoff, 30W until temperature cut-off reach then 20W) and esophageal lesions.
University of Washington
Attached you will find the abstract from the University of Washington which reviews their historical data with a single sensor probe and their more recent data with CIRCA MSP. All patients had endoscopy post-procedure.
Radiofrequency Energy Delivery
- 18F Esophageal Stethoscope, Cutoff at 0.2C rise, 33.9% Esophageal lesions
- CIRCA, 37.5C Cutoff, 16% Esophageal lesions
With Cryoablation Energy Delivery
- 18F Esophageal Stethoscope, Cutoff at 30C, 25% Esophageal lesions
- CIRCA, 25C Cutoff, 0% Esophageal lesions
