Key result
Catheter ablation for AF in CHD maintains sinus rhythm in ~33% at one year despite frequent repeat procedures.
Why the study?
AF is an evolving clinical concern in adults with congenital heart disease that can be difficult to manage medically, but few reports have evaluated the efficacy of catheter ablation in this setting.
Does catheter ablation improve freedom from atrial fibrillation in patients with congenital heart disease?

Does catheter ablation improve freedom from atrial fibrillation in patients with congenital heart disease?
Catheter ablation for atrial fibrillation in patients with congenital heart disease has a modest 1-year success rate after a single procedure, often requiring multiple procedures to maintain sinus rhythm.
Modest single-procedure success in congenital heart disease AF warrants caution; leaves open comparative effectiveness versus medical therapy.

Guarguagli et al. (2019) conducted a cohort in Atrial fibrillation in congenital heart disease (n=58). Catheter ablation was evaluated on Sinus rhythm at 1-year from the first ablation. Catheter ablation for atrial fibrillation in congenital heart disease resulted in 32.8% of patients remaining in sinus rhythm at 1 year, with 60% requiring multiple procedures.
