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.
