Pattern of ventricular septal defects and associated complications.

Abstract

Perimembranous (PM) VSD is the commonest type of ventricular septal defect presenting to a tertiary care hospital. The incidence of AVP and AR is high (10.8%) and was found almost entirely in perimembranous outlet VSDs rather than DCSA. This observation has special implication in Pakistan where pool of unoperated VSDs is large.
