Structured PICO
Does Circumferential Pulmonary Vein Isolation (CPVI) alone restore sinus rhythm in patients with long-standing persistent atrial fibrillation?

Population
Patients with long-standing persistent atrial fibrillation (AF)

Circumferential Pulmonary Vein Isolation (CPVI)
O
Outcome
Restoration of sinus rhythm (SR)surrogate
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.
Abstract
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.
