Abstract

Abstract: Deviation of the esophagus during atrial fibrillation (AF) ablation can reduce esophageal injury. This study reports upon a novel esophageal retractor that utilizes vacuum suction and mechanical deflection to deviate the esophagus. The device was used in seven patients undergoing cryoballoon AF ablation. The esophagus was deviated 31.9 ± 4.4 mm to the right and 28.2 ± 5.9 mm to the left. Endoscopy at 4.4 ± 1.5 days postablation showed no esophageal injury. This study demonstrates the safe and effective deviation of the esophagus without a trailing edge with an esophageal retractor utilizing vacuum suction and mechanical deflection.
