What views of the Left Ventricle are demonstrated in the PLAX view?

In the parasternal long-axis (PLAX) view, the left ventricle is optimally visualized, providing crucial information about its structure and function. This view allows for a comprehensive assessment of the left ventricular walls, specifically the anteroseptal and inferolateral walls.

The anteroseptal wall is located at the junction of the anterior wall and the interventricular septum, while the inferolateral wall lies along the inferolateral aspect of the left ventricle. The PLAX view captures these segments by creating a cross-section through the heart that includes these regions, enabling clinicians to evaluate conditions such as ischemic heart disease or assess for wall motion abnormalities.

Understanding the specific segments visualized in the PLAX view is critical for accurate echocardiographic assessment, as recognizing which walls are being imaged informs the interpretation of heart function and potential pathologies.
