Background Increased peak luminal esophageal temperature (LET) is associated with
increased risk of esophageal injury after left atrial posterior wall (LAPW) ablation. The …

Background Proactive cooling with a novel cooling device has been shown to reduce
endoscopically identified thermal injury during radiofrequency (RF) ablation for the treatment …

Introduction Neither the actual in vivo tissue temperatures reached with 90 W/4 s‐very high‐
power short‐duration (vHPSD) ablation for atrial fibrillation nor the safety and efficacy profile …

Background—Luminal esophageal temperature (LET) monitoring is one strategy to minimize
esophageal injury during atrial fibrillation ablation procedures. However, esophageal …

Single vs Multi‐Sensor ETM in AF Ablation Background Radiofrequency (RF) ablation in the
posterior left atrium has risk of thermal injury to the adjacent esophagus. Increased …

Background: Low radiofrequency powers are commonly used on the posterior wall of the left
atrium for atrial fibrillation ablation to prevent esophageal damage. Compared with higher …

Introduction Ablation index (AI), a novel parameter defining energy application at single
ablation lesions, calculated by integration of ablation time, energy, catheter stability, and …

Risks to collateral structures exist with radiofrequency (RF) ablation of the left atrium to
obtain pulmonary vein isolation (PVI) for the treatment of atrial fibrillation. Passive luminal …

Introduction The IMPACT study established the role of controlled esophageal cooling in
preventing esophageal thermal injury during radiofrequency (RF) ablation for atrial …

Background—It is common practice to empirically limit the radiofrequency (RF) power when
ablating the posterior left atrium during atrial fibrillation ablation to avoid thermal injury to the …
