A newborn baby is severely cyanotic. An echocardiogram reveals transposition of the great arteries. Which of the following occurs with this defect?

Question

Quizplus · Accepted Answer

Transposition of the great arteries occurs when the aorta leaves the right ventricle and the pulmonary artery leaves the left ventricle, leading to a lack of oxygenated blood reaching the body. This is incompatible with life unless there is an associated defect that allows for mixing of oxygenated and deoxygenated blood, such as a ventricular septal defect or atrial septal defect.
