Arrhythmia mechanisms and results of transcatheter ablation therapy in patients diagnosed with CHD: the most difficult and dark side of paediatric electrophysiology

Despite the complex anatomy, age, operations, and limited vascular access possibilities in patients diagnosed with CHD, transcatheter ablation treatment with advances in electrophysiology, the introduction of different energy types, special ablation catheters, multipolar mapping catheters, and 3D nonfluoroscopic mapping systems seems to be a safe and effective option.
