Why the study?
Does adjunctive left atrial posterior wall isolation using cryoballoon ablation improve clinical outcomes compared to PVI only in patients with persistent atrial fibrillation?
Does adjunctive left atrial posterior wall isolation using cryoballoon ablation improve clinical outcomes compared to PVI only in patients with persistent atrial fibrillation?
Adjunctive posterior wall isolation using cryoballoon ablation improves clinical outcomes without increasing complications compared to PVI alone in patients with persistent atrial fibrillation.
Supports adjunctive PWI by CBA in persistent AF; extends cryoballoon strategies beyond PVI alone.
