PSAX
Also written as: PSAX — Parasternal Short-Axis
Parasternal short-axis echocardiographic view used to assess left ventricular function and valve morphology.
Full Definition
The parasternal short-axis (PSAX) view is a fundamental echocardiographic imaging plane obtained by rotating the transducer 90 degrees from the parasternal long-axis position. This view provides cross-sectional images of the heart at various levels, including the aortic valve, mitral valve, and left ventricular cavity. It is essential for assessing regional wall motion, measuring chamber dimensions, and evaluating valve function, particularly for quantifying aortic stenosis and regurgitation.
Usage
Usage note: Specify the level (aortic valve, mitral valve, papillary muscle, or apex) when describing PSAX findings.
In Context
- "The PSAX view at the papillary muscle level demonstrated normal left ventricular contractility." — echocardiography report
- "Color Doppler in the PSAX view revealed moderate aortic regurgitation." — valve assessment
