Improving Oesophageal Protection During AF Ablation (IMPACT)
Esophageal Diseases
About this trial
This is an interventional prevention trial for Esophageal Diseases focused on measuring Esophageal protection, Ablation-related thermal injury, Catheter ablation for AF, Persistent AF ablation
Eligibility Criteria
Inclusion Criteria:
• Any AF patient planned for a catheter ablation procedure or a left atrial ablation protocol that puts them at risk of surrounding structural trauma, including oesophageal injury.
Exclusion Criteria:
- Patients at the age extremities will not be approached for the study. (Paediatric patients or young adults (<aged 18) or older adults over the age of 85)
- Patients having simple or non-left atrial ablation procedures not needing oesophageal protection.
- Patients at high risk of oesophageal bleeding e.g. oesophageal varices.
Sites / Locations
- St.George's HospitalRecruiting
Arms of the Study
Arm 1
Arm 2
Experimental
Active Comparator
Study Group- esophgeal cooling
Control group- esophgeal temperature probe
In this study arm, the participants will have esophageal protection during their catheter ablation procedure, utilizing the esophageal cooling device (Attune Medical, Chicago, IL). During catheter ablation, the cooling device is set to cooling levels.
In this control group, the participants will have esophageal protection utilizing the standard method in current practice, which is an esophageal temperature probe. If recorded temperatures rise above 38 degrees during ablation, ablation treatment is halted in this region.
