Echo basics: Parasternal Views
Echocardiography Views
Patient position coupled with probe placement and orientation for optimal parasternal long-axis (PLAX) and parasternal short-axis (PSAX) views. See next post for apical and subcostal views
PARASTERNAL LONG-AXIS (PLAX) VIEWS – Obtaining an optimal image
- Patient position: lying on left side, left arm raised, raise the back of the bed or use pillows under the left shoulder
- Probe position: 4th intercostal space, left sternal edge
- Probe orientation: notch towards patient’s right shoulder

PARASTERNAL LONG-AXIS (PLAX) VIEWS – PLAX inflow view
- Patient position: lying on left side, left arm raised, raise the back of the bed or use pillows under the left shoulder
- Probe position: 4th intercostal space, left sternal edge
- Probe orientation: notch towards patient’s right shoulder
PARASTERNAL LONG-AXIS (PLAX) VIEWS – PLAX outflow view
- Patient position: lying on left side, left arm raised, raise the back of the bed or use pillows under the left shoulder
- Probe position: 4th intercostal space, left sternal edge
- Probe orientation: notch towards patient’s right shoulder
PARASTERNAL SHORT-AXIS (PSAX) VIEWS – PSAX aortic valve view
- Patient position: lying on left side, left arm raised, raise the back of the bed or use pillows under the left shoulder
- Probe position: 4th intercostal space, left sternal edge
- Probe orientation: notch towards patient’s left shoulder
Tilt probe upwards towards head to show aorta as a circle.
PARASTERNAL SHORT-AXIS (PSAX) VIEWS – PSAX mitral valve view
- Patient position: lying on left side, left arm raised, raise the back of the bed or use pillows under the left shoulder
- Probe position: 4th intercostal space, left sternal edge
- Probe orientation: notch towards patient’s left shoulder
Tilt probe downwards towards spine to show left ventricle as a perfect circle.
PARASTERNAL SHORT-AXIS (PSAX) VIEWS – PSAX papillary muscle view
- Patient position: lying on left side, left arm raised, raise the back of the bed or use pillows under the left shoulder
- Probe position: 4th intercostal space, left sternal edge
- Probe orientation: notch towards patient’s left shoulder
Tilt the probe even further towards the spine keeping the left ventricle as a circle but showing the papillary muscles instead of the mitral valve.
