Ventricular septal defect

Ventricular septal defect is a congenital defect of the heart, that occurs as an abnormal opening in the wall that separates the right and left ventricles. Ventricular septal defect may also be associated with other heart defects. Many small defects will close on their own. For those defects that do not spontaneously close, the outcome is good with surgical repair.
