Comparison of efficacy and safety of laser balloon and cryoballoon ablation for atrial fibrillation—a meta-analysis

Background Laser balloon(LB) and cryoballoon (CB) ablationare two balloon-based catheter ablationtechnologies used for atrial fibrillation (AF) ablationin recent years. However, the efficacy and the safety of LB ablationin comparison to CB ablationremained indeterminate. We sought to compare these two technologies by conducting meta-analysis of previous studies using both the CB and LB ablationsystems for AF ablation.
