Abstract P2101: Time Dependence Of Esophageal Injury With And Without Proactive Cooling During High-power Short-duration Radiofrequency Ablation
Background: Recent data suggest that luminal esophageal temperature (LET) monitoring during high-power short-duration (HPSD) ablation may be inadequate to prevent esophageal thermal injury during radiofrequency (RF) ablation. This is due in part to delayed responses to thermal latency and the ...
Influence of tissue thickness on thermal latency during high-power short-duration radiofrequency ablation with proactive esophageal cooling
Background
Thermal latency, or delayed heating, is increasingly recognized as an important factor in the formation of both intentional and unintentional lesions during radiofrequency (RF) ablation for the treatment of atrial fibrillation (AF). High-power short-duration (HPSD) ablation appears to...
Abstract 10771: Avoidance of Lethal Isotherm Formation in Esophageal Tissue with an Active Cooling Device Under High-Power, Short-Duration Ablation
Introduction: Atrioesophageal fistula (AEF) is a severe complication of left atrial ablation for the treatment of atrial fibrillation. Thermal injury is the proposed mechanism, and a potential pathway occurs through exceeding the lethal isotherm of esophageal tissue in contact with the left atri...
Proactive Esophageal Cooling Protects Against Thermal Insults During High-Power Short-Duration Radiofrequency Ablation
Background
Proactive cooling with a novel cooling device has been shown to reduce endoscopically identified thermal injury during radiofrequency (RF) ablation for the treatment of atrial fibrillation using medium power settings. We aimed to evaluate the effects of proactive cooling during high-power short-duration (HPSD) ablation.
Methods
A computer model accounting for the left atrium ...
