Summary

Ventricular septal defects (VSDs) are common in newborns, with most muscular VSDs closing spontaneously. The long-term prognosis for VSD is favorable, with a low mortality rate primarily linked to other health conditions.

Area of Science:

  • Pediatric Cardiology
  • Neonatal Medicine
  • Congenital Heart Defects

Background:

  • Ventricular septal defect (VSD) is a common congenital heart anomaly.
  • Understanding the prevalence and long-term outcomes of neonatal VSD is crucial for clinical management.

Purpose of the Study:

  • To determine the incidence of VSD in newborns.
  • To evaluate the long-term follow-up and spontaneous closure rates of neonatal VSD.

Main Methods:

  • A retrospective study of 222 newborns diagnosed with VSD between 1991 and 1996.
  • Echocardiography was used for diagnosis and defect characterization.
  • Follow-up ranged from 1 to 72 months.

Main Results:

  • The incidence of VSD was 7.19 per 1,000 newborns.

  • Muscular VSDs were most common (79.7%), with smaller mean defect size compared to perimembranous VSDs.
  • Spontaneous closure occurred in 79.3% of VSDs, predominantly muscular defects, by 24 months of age.

    • Conclusions:

    • Muscular VSDs are the most frequent type in neonates and have a favorable prognosis.
    • High rates of spontaneous closure and low mortality underscore a positive outlook for neonatal VSD.
    • Mortality is mainly associated with extracardiac anomalies, not the VSD itself.
