Which walls of the left ventricle are demonstrated in the PLAX view?

In the parasternal long-axis (PLAX) view, the most prominent walls of the left ventricle that are visualized are the inferolateral wall and the anterior wall. The PLAX view aligns the ultrasound beam along the long axis of the left ventricle, making it optimal for examining these two specific regions.

The inferolateral wall, in particular, is visualized as the lateral portion of the left ventricle in this view. This wall is critically important because it can be involved in various cardiac conditions, including ischemic heart disease and heart failure.

Understanding the anatomy presented in the PLAX view is essential for echocardiographic assessment, as it helps in evaluating wall motion abnormalities and overall left ventricular function.
