Background: 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.
Methods: We performed a comprehensive search on catheter ablation for atrial fibrillation in congenital heart disease up until July 2019 through several electronic databases.
Results: Ablation of AF in patients with CHD had a modest 12 months AF freedom ranging from 32.8% to 63%, which can be increased by subsequent/repeat ablation. The complexity of CHD appears to have a significant effect on a study but not in others. Catheter ablation in ASD and persistent left superior vena cava had a high success rate. Overall, catheter ablation is safe whichever the type of CHD is.
Conclusion: Catheter ablation for AF in CHD had modest efficacy that can be increased by subsequent/repeat ablation and it also has an excellent safety profile. Ablation in complex CHD could also have similar efficacy, however, it is preferably done by experts in a high volume tertiary center.

Background: Catheter ablation (CA) is an effective therapeutic option for patients with symptomatic atrial fibrillation (AF). Previous studies have reported silent cerebral lesions (SCLs) detected by magnetic resonance imaging (MRI) after different CA techniques; however, the results were controversial. Therefore, we performed this network meta-analysis (NMA) to assess the incidence of SCLs after cryoballoon, hotballoon, laserballoon, and radiofrequency ablation (RFA).

Background: Cardioneuroablation (CNA) is a new approach to treat reflex syncope and functional bradyarrhytmias caused by autonomic imbalance. We report our experience using CNA.
Method: From September 2022 to July 2023, we took care of 21 patients (mean age 42 ± 21 years; 62% male) affected by reflex syncope or functional bradyarrhythmias.

Despite significant advances in its management, AF remains a major healthcare burden affecting millions of individuals. Rhythm control with antiarrhythmic drugs or catheter ablation has been shown to improve symptoms and outcomes in AF patients, but current treatment options have limited efficacy and/or significant side-effects. Novel mechanism-based approaches could potentially be more effective, enabling improved therapeutic strategies for managing AF.
