Recovery of cardiogenic shock with ablation of incessant tachycardia in a neonate

Abstract

Supraventricular tachycardia (SVT) is one of the most common conditions in neonates that require emergency cardiac care. Its incidence in infancy is 0.06 and 0.25 per 1000 patients per year by the age of 1 month and one year respectively. The symptoms are usually nonspecific and include poor feeding, irritability, vomiting, cyanosis, and pallid spells. If the symptoms are unrecognized for hours to days, the infant can present with significant hemodynamic compromise or heart failure. Despite the success of conservative management in most cases, catheter ablation is required in cases of failure of medical treatment. We report a case of SVT ablation using a single catheter in a neonate who presented with tachycardia-inducedcardiomyopathy (TIC).
