Cryoballoon Ablation for Elderly Patients With Atrial Fibrillation: Results From the Korean Cryoballoon Registry.

ABSTRACT:

Background and objectives

Cryoballoon ablation (CBA) is considered an effective rhythm control treatment for atrial fibrillation (AF) and is increasing exponentially. However, data regarding the efficacy and safety of CBA in elderly patients are limited.

Methods

A total of 2,652 patients (55.2% with non-paroxysmal AF) from the Korean CBA registry database with follow-up of ≥12-months after de novo CBA were divided into 2 groups based on age (<75 and ≥75 years old). Procedure related complications and clinical outcomes were compared.

Results

Compared to the control group (n=2,403), the elderly group (n=249) had female predominance (41.8% vs. 21.1%, p<0.001), a higher CHA₂DS₂-VASc scores (4.0 [3.0-5.0] vs. 2.0 [1.0-3.0]; p<0.001), and a higher prevalence of heart failur
