Study population
From 2012 to 2018, 911 young patients (< 18 years old)
underwent a catheter ablation of an accessory pathway at two
international tertiary electrophysiology centers (Antwerpen University
Hospital, Antwerpen, Belgium and Bristol Royal Hospital for Children,
Bristol, UK). Patients with an acute failure, or successful ablation
with subsequent recurrence were included in this retrospective study.
