Incidence of death related vsd?

It would be very helpful if you gave more info... size of defect, age of patient...infant, child, or adult. There are thousands of people walking around with vsd's. Infants born with vsd may need surgery if it is large, but many septal defects close on their own. Go to Webmd.com and enter "ventricular septal defect". There are many good articles. A vsd alone does not put a person at high risk. Of course, the best source of info. is a cardiologist or pediatric cardiologist.
