Risk factors

It is not known why ventricular septal defects occur, but some congenital heart defects appear to be inherited and sometimes occur with other genetic problems such as Down syndrome. If you have a heart defect or have a child with a heart defect, a geneticist can assess the likelihood of future children developing the defect.
