Defects in the interventricular septum can be large or small and may be congenital or acquired, as in patients after myocardial infarction. The ventricular septum has a superior membranous portion and an inferior muscular component and each may be associated with abnormalities. The defects are among the most common congenital cardiac anomalies in infants and children.

You Will Learn

  • To define the types and frequencies of VSD locations
  • To assess the determinants of shunt size in VSD
  • To recognize the associations and clinical features of VSD
  • To calculate shunt fractions using data derived from patients with VSD.
  • To interpret angiographic, hemodynamic, and oximetry data in VSD from the cardiac cath lab
