Cryoballoon versus radiofrequency ablation for persistent atrial fibrillation: an updated systematic review and meta‑analysis.

ABSTRACT:

Background

Compared with paroxysmal atrial fibrillation, persistent atrial fibrillation (AF) is more harmful and difficult to treat, and the efficacy of different catheter ablation for both also varies greatly. So this study aimed to systematically evaluate the efficacy and safety of cryoballoon (CB) and radiofrequency (RF) ablation in the treatment of persistent AF.

Methods

We searched the PubMed, Embase, and Cochrane library databases for studies comparing the efficacy and safety between CB and RF ablation for persistent AF. All included studies met our inclusion criteria.

Results

A total of 11 studies, 2551 patients were enrolled in this study, including 1256 patients in CB group and 1295 patients in RF group. Meta-analysis results showed that the freedom from atri
