Efficacy and safety of catheter ablation for atrial fibrillation in congenital heart disease - A systematic review and meta-analysis.

Prevalence of atrial fibrillation (AF) in patients with congenital heart disease (CHD) is on the rise. Anti-arrhythmic drugs are usually the first line of treatment in CHD, however, it is often ineffective and poorly tolerated. We aimed to perform a systematic review to assess the efficacy and safety of catheter ablation for AF in CHD.
