Which tomographic plane of the heart displays all walls of the left ventricle?

The short axis tomographic plane of the heart is specifically designed to display all walls of the left ventricle in a comprehensive manner. In this imaging technique, slices are taken perpendicular to the long axis of the heart, allowing for the visualization of the left ventricle's anatomical structure at various levels.

In short axis views, multiple slices can be obtained at different heights along the ventricle, providing a clear depiction of the anterior, lateral, inferior, and septal walls. This orientation is particularly useful for assessing ventricle function, identifying wall motion abnormalities, and evaluating conditions such as ischemic heart disease.

Other plane options may not achieve the same effectiveness. For example, the horizontal long axis primarily visualizes longitudinal structures and does not provide a complete cross-sectional view of the ventricle walls. The vertical long axis also focuses on a particular orientation and may not highlight all walls as thoroughly. The transaxial option is less commonly used in standard cardiac imaging and doesn't specifically target the left ventricle's walls like the short axis does. Thus, the short axis is the optimal choice for this purpose.
