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...
