Catheter ablation for an incessant arrhythmia in a preterm low-weight neonate.

UNLABELLED: A 15-day-old neonate weighing 1800 g presented with incessant long-RP tachycardia. Temporary cessation of the arrhythmia with adenosine confirmed the diagnosis of permanent junctional reciprocating tachycardia (PJRT). The arrhythmia was refractory to multiple drugs. An electrophysiological study confirmed diagnosis. The arrhythmia was successfully treated with radiofrequency.

LEARNING

OBJECTIVE

Transcatheter radiofrequency ablation can be done safely in infants who are unresponsive to medical therapy, regardless of age and body weight.
