Pre-excitation cardiac problems in children: recognition and treatment

Conclusion: For ventricular pre-excitation co-exists with dilated cardiomyopathy, differential diagnosis of tachycardiomyopathy or accessory pathway-induced dilated cardiomyopathy should be considered. Catheter ablation (radiofrequency and cryoablation) is a relatively safe and effective treatment option and has become the first choice to treat children with ventricular pre-excitation.What is Known:• Persistent atrioventricular reentrant tachycardia in children can lead to tachycardiomyopathy;• Antiarrhythmic drugs that can be chosen for children are quite limited.What is New:• The anterograde conduction of right accessory pathway (not related to supraventricular tachycardia) might lead to accessory pathway-induced dilated cardiomyopathy.• Catheter ablation (including radiofrequency and cryoablation) has become the first choice for children with pre-excitation syndrome.
