CAMRT Radiography Practice Exam

Which condition is characterized by a combination of ventricular septal defect, right ventricle outflow obstruction, and a displaced aorta?

1. Atrial fibrillation

2. Tetralogy of Fallot

3. Mitral valve prolapse

4. Coronary artery disease

The correct answer is: Tetralogy of Fallot

The condition described is characterized by four key features, namely a ventricular septal defect, right ventricular outflow obstruction, an aorta that is displaced, and right ventricular hypertrophy, which together define Tetralogy of Fallot. This congenital heart defect is one of the most common types of cyanotic heart disease and typically presents in infancy or early childhood. The ventricular septal defect allows blood to flow between the left and right ventricles, leading to oxygen-poor blood being mixed with oxygen-rich blood, which can contribute to the cyanosis often seen in this condition. The right ventricular outflow obstruction (due to narrowing at or just below the pulmonary valve) impedes proper blood flow from the right ventricle to the lungs, further affecting oxygenation. The aorta being displaced means that instead of arising solely from the left ventricle, the aorta straddles the left and right ventricles, allowing it to receive blood from both chambers. In contrast, atrial fibrillation primarily affects the heart's rhythm and is not related to structural defects. Mitral valve prolapse involves the improper closure of the mitral valve but does not include the specific anatomical issues seen in Tetralogy of Fallot. Coronary artery disease
