Radiofrequency ablation of supraventricular tachyarrhythmias in newborns and infants: why, when, and how?

ABSTRACT: Supraventricular tachyarrhythmias (SVTs) in newborns and infants (< 1 year) can usually be managed with antiarrhythmic drug therapy and often resolve spontaneously within the first year of life. However, some SVTs may be drug-refractory, leading to hemodynamic instability or tachycardia-induced cardiomyopathy, necessitating catheter ablation. Refinements in ablation techniques like electro-anatomical mapping and increased expertise have made catheter ablation an effective option for young children (< 5 years). Nonetheless, due to a lack of large-scale studies involving newborns and infants (< 1 year), concerns persist regarding the risk of major complications associated with ablation energy in small hearts. Potential risks include coronary artery lesions, valve damage, vessel injury, compl
