Key result
Novel respiratory maneuver enables ~65% completion of planned cryoapplication despite sharp esophageal temperature drops.
Why the study?
Esophageal injury from critical luminal cooling is a complication of cryoballoon ablation for atrial fibrillation, prompting the evaluation of a novel breathing maneuver for active esophageal temperature control.
Does a special breathing maneuver prevent critical esophageal temperature drops during cryoballoon ablation in patients with atrial fibrillation?
Observational (n=70)
Does a special breathing maneuver prevent critical esophageal temperature drops during cryoballoon ablation in patients with atrial fibrillation?
A novel breathing maneuver during cryoballoon ablation for atrial fibrillation may help manage critical esophageal temperature drops and allow completion of cryoapplication.
May facilitate cryoapplication completion during esophageal cooling; hypothesis-generating and requires prospective validation before clinical adoption.

Сорокин et al. (2022) conducted an observational in Atrial fibrillation (n=70). Respiratory maneuver was evaluated on Completion of planned cryoapplication duration. A novel respiratory maneuver allowed completion of the planned cryoapplication duration in 11 of 17 cases (64.7%) with sharp esophageal temperature drops during cryoballoon ablation.
