Congenital heart defect (CHD) is a flaw in the structure of the heart and great vessels of a newborn. Most CHDs either obstruct blood flow to the heart or nearby vessels or cause blood to flow through the heart in an abnormal pattern. Though such defects occur in less than 1% of the population, they are the leading cause of birth defect-related deaths. There are 8 defects that comprise the bulk of all CHDs, with ventricular septal defects presenting most commonly.
