Early Cryoablation After First Diagnosis of Atrial Fibrillation Reduces Arrhythmia Recurrence in Heart Failure Patients.

ABSTRACT:

Background

Atrial fibrillation (AF) and heart failure (HF) often coexist, leading to increased mortality. A cryoballoon-based approach is a potential treatment for patients with HF because of its safety and efficacy.

Objectives

The authors sought to evaluate the optimal timing of cryoballoon ablation after the first clinical diagnosis of AF and its prognosis for patients with HF.

Methods

This large-scale multicenter study retrospectively collected data of patients with HF who underwent cryoballoon ablation for AF from 17 Japanese institutions. Patients were divided into 2 groups depending on the duration between the first diagnosis and ablation using a median time of 0.5 year (IQR: 0.3-2.0 years). Clinical endpoints of recurrence, mortality, and HF hospitalization wer
