Why the study?
Post-ablation chest pain is common after RF PVI for AF, and active esophageal cooling has pleiotropic effects that may mitigate inflammation and reduce post-ablation chest pain.
Does active esophageal cooling reduce post-ablation chest pain in patients undergoing radiofrequency pulmonary vein isolation for atrial fibrillation?
Population
183 patients undergoing RF PVI for AF
Comparison
Post-adoption of active esophageal cooling vs pre-adoption
Design
Registry-based pre-post cohort study

Active esophageal cooling may reduce post-ablation chest pain; leaves open its role in routine AF ablation.
Does active esophageal cooling reduce post-ablation chest pain in patients undergoing radiofrequency pulmonary vein isolation for atrial fibrillation?
The adoption of active esophageal cooling during radiofrequency ablation for atrial fibrillation was associated with a complete elimination of post-ablation chest pain, compared to a 45.6% incidence in historical controls.
Zagrodzky et al. (2023) studied this question.
