Background: Patients with transposition of the great arteries (TGA) who undergo atrial switch procedures may develop symptomatic atrial arrhythmias necessitating ablation. We present a single-centre retrospective analysis of a novel approach using jugular access for catheter ablation in this unique patient population., Methods: A 5-year retrospective analysis was conducted on patients referred for atrial arrhythmia ablation following atrial switch procedures. Procedures were performed by experienced operators, and data on patient demographics, procedural characteristics, and outcomes were collected. Statistical analysis was performed to compare outcomes between jugular and femoral access groups., Results: Jugular access (N = 9) and femoral access (N = 13) cohorts were comparable in age, gender distribution, and clinical characteristics. Procedural success rates were high in both groups, with no significant difference in recurrence rates. Jugular access demonstrated a comparatively safe profile compared to femoral access., Discussion: The jugular approach offers a viable alternative to femoral access for atrial arrhythmia ablation in patients with atrial switch procedures. The trajectory from the internal jugular vein to the baffle is straightforward, reducing vascular complications. Success rates and procedural times were comparable, highlighting the feasibility and safety of the jugular approach. The option for rapid post-procedural mobilisation adds to its appeal., Conclusion: Atrial arrhythmia ablation with jugular access in patients with atrial switch procedures is safe and effective, providing an alternative in cases where femoral access may pose challenges. This approach warrants consideration in the management of atrial arrhythmias in this unique patient population., Competing Interests: Declarations. Ethical approval: Not required.
