Electrophysiology assessment and radiofrequency ablation of arrhythmias in adult patients with congenital heart defects: the Christchurch experience.

Introduction: Adults with congenital heart disease (CHD) frequently have cardiac arrhythmias, many of which are best treated with radiofrequency ablation (RFA). We present our experience in this group.

Methods: Retrospective chart based review of diagnosis, arrhythmia type, results of cardiac electrophysiological assessment, and procedural and long-term clinical success of radiofrequency ablation.
