Segmental nonocclusive cryoballoon ablation of pulmonary veins and extrapulmonary vein structures: Best practices III
Key result
Segmental nonocclusive cryoballoon ablation effectively targets extra-pulmonary vein structures in AF.
Why the study?
Although cryoballoon ablation of AF traditionally relied on PV occlusion, growing interest surrounds segmental, nonocclusive cryoballoon ablation targeting large/common PVs and extra-PV structures.

Implication
Hypothesis-generating for extra-PV ablation in AF; leaves open need for randomized trials before practice change.
Structured PICO
P
Population
Patients with atrial fibrillation, particularly persistent AF
I
Intervention
Segmental, nonocclusive cryoballoon ablation targeting large/common pulmonary veins and extra-pulmonary vein structures (left atrial roof and posterior wall) in conjunction with pulmonary vein isolation
This review outlines best practices and the rationale for using segmental, nonocclusive cryoballoon ablation to target extra-pulmonary vein structures in patients with atrial fibrillation.
Cite This Study
Aryana et al. (2021) conducted a review in Atrial fibrillation. Segmental, nonocclusive cryoballoon ablation was evaluated. Segmental, nonocclusive cryoballoon ablation provides an effective approach for targeting extra-pulmonary vein structures like the left atrial roof and posterior wall in atrial fibrillation.
