Abstract

Abstract Management of left-sided accessory pathways (APs) is based on catheter ablation through an antegrade or retrograde approach. Both are safe and effective but are associated with exposure to x-rays; however, recipients of ablation are generally young. We sought to evaluate the impact of the approach chosen on dose–area product (DAP). A total of 95 patients who underwent radiofrequency ablation of a left-sided AP between January 2011 and January 2020 were included. The primary endpoint was the radiation dose received by the patient. Secondary endpoints were procedural success and complication and recurrence rates. The mean age of the study population was 34.3 ± 16.6 years. The antegrade transseptal approach was used in 63.5% of cases. By multivariate analysis, the antegrade transseptal approach was associated with a 53% reduction in DAP ( p < 0.001). The radiation dose received was also significantly associated with body mass index and total fluoroscopy time ( p < 0.001). There was no significant difference in other secondary endpoints between approaches. The use of an antegrade transseptal approach is associated with a significant reduction in DAP compared with the retrograde approach, and procedural success and complication and recurrence rates are similar.
