Emergent radiofrequency ablation of the AV node may be a viable treatment for neonates with unstable, medically refractory supraventricular tachycardia.
Emergent AV nodal ablation may serve as rescue in unstable neonates with refractory SVT; this case leaves open questions of safety and alternatives.
Supraventricular tachycardia due to accessory atrioventricular connections in infants is usually well-tolerated. Rarely an infant can have supraventricular tachycardia that is incessant and refractory to medical therapy. We describe a patient with supraventricular tachycardia detected prenatally that caused severe cardiac dysfunction and hemodynamic instability after birth.
