Supraventricular tachycardia as a presenting feature of volvulus in a 15-month-old boy

Neonatal supraventricular tachycardia and necrotizing enterocolitis: case report and literature review

BACKGROUND

Necrotizing enterocolitis (NEC) and supraventricular tachycardia (SVT) are serious emergencies in the neonatal period. Although these conditions are recognized as distinct pathologies, literature reports suggest that recurrent episodes of SVT may predispose patients to NEC via disturbances in mesenteric blood flow and a decrease in tissue perfusion.

CASE PRESENTATION

We present a case of a preterm infant affected by recurrent episodes of SVT who developed the initial stage of NEC on the 17th day of life. Moreover, a detailed description of all the cases described in the literature is reported.

MATERIALS AND METHODS

An integrative review of the updated literature in the Medline database and PubMed and scientific books and articles was conducted. The research from October 2019 to December 2019 was searched for with MeSH and free terms (necrotizing enterocolitis, supraventricular tachycardia) and was linked by Boolean operators.

CONCLUSIONS

SVT can be considered a risk factor for the development of NEC. Therefore, clinicians should have a high level of suspicion for NEC in infants affected by SVT. This article is the first structured literature review analysing the association between SVT and NEC.

Recurrent supraventricular tachycardia and necrotizing enterocolitis: A causative role or a simple association? A case report and literature review

Insufficiency in mesenteric flow is a risk factor for the development of necrotizing enterocolitis (NEC). Recurrent episodes of supraventricular tachycardia (SVT) can lead to gut ischemia, with subsequent reperfusion injury. We present a term infant who developed NEC at 37 days of life after refractory SVT and reverted to sinus rhythm on day 23 and 25 of life. Resected stenotic ileum and transverse colon demonstrated inflammation with ischemia. This is the first case of NEC following SVT in a term infant without a congenital morphologic abnormality. In view of the temporal sequence of events, and in the absence of other risk factors for NEC, the SVT and NEC were likely causally related.
