Adult Echocardiography Practice Exam

This parasternal short axis image is taken at what level?

1. Papillary muscle

2. Base

3. Aortic

4. Apex

The correct answer is: Papillary muscle

The parasternal short-axis view is a commonly used echocardiographic perspective that allows visualization of different structures of the heart. When the image is taken at the level of the papillary muscles, it typically captures the left ventricle's internal structures, providing a view of the walls and valves in relation to those muscles. In the short-axis view taken at the papillary muscle level, the echocardiographer can assess the condition of the left ventricle, inspect the mitral valve and its functioning, and evaluate wall motion. This particular level is significant for understanding the dynamics of the heart's pumping action, as the papillary muscles are integral to the mitral valve apparatus, influencing valve function during the cardiac cycle. Other levels like the base and apex also provide important information, but they visualize different areas of the heart. The base level typically shows the aortic valve and adjacent structures, while the apex captures the innermost portions of the ventricles. Each level offers its unique insights, but the papillary muscle level is especially important for evaluating mitral valve function and overall ventricular performance, thus making it the correct answer in this context.
