Congenital heart defect (CHD) or congenital heart anomaly is a defect in the structure of the heart and great vessels which is present at birth. Many types of heart defects exist most of which either obstruct blood flow in the heart or vessels near it or cause blood to flow through the heart in an abnormal pattern. Other defects such as long QT syndrome affect the heart’s rhythm. Heart defects are among the most common birth defects and are the leading cause of birth defect-related deaths.
