PLAX
Also written as: PLAX — Parasternal Long-Axis
Parasternal long-axis echocardiographic view used to assess left ventricular function and aortic valve morphology.
Full Definition
The parasternal long-axis view is a standard echocardiographic imaging plane obtained from the left parasternal border. This view provides optimal visualization of the left ventricle, left atrium, aortic root, and mitral valve in a longitudinal plane. It is essential for measuring left ventricular dimensions, assessing wall motion, and evaluating aortic and mitral valve function. The PLAX view is typically the first imaging plane acquired during a comprehensive echocardiographic examination.
Usage
Usage note: Always capitalize when used as an abbreviation; lowercase when spelled out as 'parasternal long-axis view'.
