Does esophageal cooling with a cooled water-irrigated intraesophageal balloon reduce luminal esophageal temperature during RF ablation in patients with drug-refractory AF?
Esophageal cooling using a cooled water-irrigated intraesophageal balloon is feasible and significantly lowers luminal esophageal temperature during AF ablation, potentially reducing the risk of thermal injury.
