Key result
Oesophageal temperature monitoring with insulated thermocouples during AF ablation resulted in a similar incidence of asymptomatic oesophageal lesions compared to no monitoring (7.5% vs 10%, P=1.0).
Why the study?
Does the use of an oesophageal temperature probe with insulated thermocouples reduce the incidence of asymptomatic oesophageal lesions in patients undergoing atrial fibrillation radiofrequency ablation?

Oesophageal temperature monitoring was not associated with fewer lesions; leaves open whether routine use improves safety in AF ablation.

p-value: p=1.0
The use of an oesophageal temperature probe with insulated thermocouples during atrial fibrillation ablation is feasible and results in a similar incidence of asymptomatic oesophageal lesions compared to ablation without temperature monitoring.
Halbfaß et al. (2016) conducted a cohort in Symptomatic, drug-refractory paroxysmal or persistent atrial fibrillation (n=80). Oesophageal temperature probe with insulated thermocouples vs. No luminal oesophageal temperature monitoring was evaluated on Asymptomatic endoscopically detected oesophageal lesions (EDEL) (p=1.0). Oesophageal temperature monitoring with insulated thermocouples during AF ablation resulted in a similar incidence of asymptomatic oesophageal lesions compared to no monitoring (7.5% vs 10%, P=1.0).
