Impact of NT-proBNP reduction on recurrence after cryoballoon pulmonary vein isolation and left atrial roof ablation in persistent atrial fibrillation.

ABSTRACT: Pulmonary vein (PV) isolation by catheter ablation is a widely used curative therapy for atrial fibrillation (AF). However, in patients with persistent AF (PeAF), long-term outcomes are poor when PV isolation is performed alone. Although left atrial (LA) roof ablation is sometimes added to PV isolation, its effectiveness and predictors of success remain unclear. To identify predictors of arrhythmia recurrence in patients with PeAF undergoing LA roof ablation and PV isolation using a cryoballoon catheter. A retrospective assessment of LA roof ablation and PV isolation using a cryoballoon was performed in 65 consecutive patients with PeAF. The median age of the patients was 69 years [Q1:61, Q3:75]; 55% were female, and 49% had longstanding PeAF. The complete LA roof block success rate using
