Question

Quizplus · Accepted Answer

These features are classic radiographic findings associated with aortic stenosis. The enlarged left ventricle is a result of increased pressure needed to pump blood through the narrowed aortic valve, while the prominent ascending arch is due to post-stenotic dilation. The small aortic knob is a result of the calcification of the valve leaflets, and valve calcification is a hallmark of aortic stenosis.
