Esophageal thermal injury in catheter ablation of atrial fibrillation.

Abstract

Pulmonary vein isolation is an established method for the catheter ablation of atrial fibrillation. Esophageal thermal injuries, such as esophageal erosion, ulceration and periesophageal nerve injury leading to gastric hypomotility, are important complications associated with pulmonary vein isolation. In this review article, we describe the mechanisms, characteristics and the predictors of esophageal thermal injury associated with pulmonary vein isolation.
