Active esophageal cooling reduces peri-esophageal and vagal nerve injury in radiofrequency-current pulmonary vein isolation.

ABSTRACT:

Background

Damage to peri-esophageal tissue may occur following pulmonary vein isolation (PVI). Active esophageal cooling has been shown to reduce the incidence of mucosal esophageal injury, probably by dissipation of heat and inhibition of inflammation. Whether it also protects the peri-esophageal vagal nerve plexus and reduces gastric hypomotility and food retention is uncertain.

Objective

The study aimed to analyze and compare the incidence of esophageal and vagal nerve injury following radiofrequency-current (RF) PVI with active esophageal cooling to that of luminal esophageal temperature (LET) monitoring.

Methods

Using endoscopy and electrogastrography, esophageal and peri-esophageal injury (mucosal lesions, food retention, and vagal nerve injury) were prospectiv
