Why the study?
Does Circumferential Pulmonary Vein Isolation (CPVI) alone restore sinus rhythm in patients with long-standing persistent atrial fibrillation?
Does Circumferential Pulmonary Vein Isolation (CPVI) alone restore sinus rhythm in patients with long-standing persistent atrial fibrillation?
CPVI alone restores sinus rhythm in less than half of patients with long-standing persistent AF, highlighting the frequent need for multiple procedures and additional ablation strategies.
May warrant additional ablation strategies beyond CPVI in long-standing persistent AF; leaves open optimal lesion sets in randomized trials.
CPVI alone is sufficient to restore SR in 43.2% of patients with long-standing persistent AF. Multiple procedures and additional ablation strategies with a significant risk of inadvertent left atrial appendage isolation are often required to maintain stable SR.
