Test Your Knowledge About Congenital Heart Defects

Congenital heart defects are structural problems with the heart that are present at birth and can affect the flow of blood through the heart. They are the most common type of birth defect.

The most common congenital cardiac anomaly in children and the second most common in adults is ventricular septal defects (VSDs).

The four categories of congenital heart defects are obstructive defects (e.g. aortic stenosis), septal defects (e.g. ventricular septal defect), cyanotic defects (e.g. Tetralogy of Fallot), and other defects (e.g. Patent ductus arteriosus).
