Key result
Cryoballoon catheter ablation significantly decreased f-wave frequency during the procedure (p=0.001), particularly after ablation of the inferior right pulmonary vein.
Why the study?
Does cryoballoon catheter ablation alter f-wave characteristics in patients with atrial fibrillation?
Observational (n=77)
Does cryoballoon catheter ablation alter f-wave characteristics in patients with atrial fibrillation?
p-value: p=0.001
Cryoballoon catheter ablation is associated with a significant decrease in f-wave frequency, which can be reliably analyzed using a signal quality index.

Cryoballoon ablation was associated with reduced f-wave frequency; hypothesis-generating for its role as a real-time marker of pulmonary vein isolation in AF.
Henriksson et al. (2018) conducted an observational in Atrial fibrillation (n=77). Cryoballoon catheter ablation vs. Before ablation (baseline) was evaluated on f-wave frequency (p=0.001). Cryoballoon catheter ablation significantly decreased f-wave frequency during the procedure (p=0.001), particularly after ablation of the inferior right pulmonary vein.
