Targeted Superior Vena Cava Isolation Combined With Pulmonary Vein Isolation Versus Pulmonary Vein Isolation Alone Using Cryoballoon Ablation for Atrial Fibrillation

Clinical Cardiology, Volume 49, Issue 9, September 2026.
Cryoballoon‐based targeted superior vena cava isolation (SVCI) added to pulmonary vein isolation (PVI) improved 12‐month freedom from atrial tachyarrhythmia compared with PVI alone (90.9% vs. 76.4%, p = 0.037) without increasing complications, supporting systematic SVC trigger assessment in atrial fibrillation ablation. ABSTRACT Background The superior
