23 Empiric versus entrained cavotricuspid isthmus line ablation in congenital heart disease: a single centre experience

Introduction: Catheter ablation for supraventricular tachycardia (SVT) in patients with congenital heart disease (CHD) is an important therapeutic option. Typical atrial flutter (AFl) is the most commonly observed atrial arrhythmia, however induction of sustained tachycardia at the time of ablation is not always possible. We hypothesized that performing an empiric cavo-tricuspid isthmus (CTI) line ablation in case of non-inducibility leads to good outcomes. Long-term outcomes of empiric versus entrained CTI ablation in CHD patients with right-sided supraventricular arrhythmias were examined.
