Calculated parameters of luminal esophageal temperatures predict esophageal injury following conventional and high-power short-duration radiofrequency pulmonary vein isolation.

For both ablation strategies, AUC of the LET curves best predicted esophageal injury. HPSD is associated with similar rates of esophageal injury when (mostly subclinical) periesophageal alterations (that are of unclear clinical relevance) are included. Whether integration of these calculated LET parameters is useful to prevent esophageal injury remains to be seen.
