Transposition of the Great Arteriesthe Aorta and the Pulmonary Artery are

reversed which prevents oxygen-richblood from properly being spread to the

rest of the body

Tetralogy of Fallothole between the left and right ventricle;

narrowing of pulmonary valve; thickening of rightventricle; aorta is mispositioned and mixesoxygen-rich blood and oxygen-poor blood

VSD: Ventricular Septal Defecta hole in the wall between the right and leftventricles of the heart which allows oxygen-rich and oxygen-poor blood to mix between

the ventricles

ASD: Atrial Septal Defecta hole in the wall between the right and leftatriums of the heart which allows oxygen-

rich and oxygen-poor blood to mix betweenthe atriums

The right atrium receives oxygen-poor blood from the body andpumps it to the right ventricle. The right ventricle pumps theoxygen-poor blood to the lungsthrough the pulmonary valve.The left atrium receives oxygen-richblood from the lungs through thepulmonary arteries and pumps it tothe left ventricleThe left ventricle pumps the oxygen-rich blood through the aortic valve tothe aorta and out to the rest of thebody.

the aortic valve is narrowed, affecting the flow ofoxygen-rich blood away from the heart; the leftventricle muscle thickens because it must work
