Wolff-Parkinson-White Syndrome in the Preterm Neonate.

Abstract

Wolff-Parkinson-White (WPW) syndrome is a rare cardiac condition arising from abnormal embryologic development of the annulus fibrosus in combination with the cardiac conduction system. The abnormality results in the development of accessory pathways and preexcitation changes which can provoke episodes of tachyarrhythmias. The most common presentation of WPW syndrome is supraventricular tachycardia. Beyond customary abortive therapy, chronic management strategies vary based upon timing and clinical severity of the initial disease presentation. Prompt diagnosis and rate control have a dramatic impact on the outcomes of morbidity and mortality. The purpose of this article is to present a case study of a preterm infant who manifested with WPW syndrome. Additionally, the article will explore the pathophysiology of WPW syndrome and the timing and presentation of common clinical manifestations of the disease, along with current diagnostic and treatment strategies to achieve optimal patient outcomes in the neonatal population.
