# Parasternal long axis echo view

Probe position and acquisition guidance for this echocardiographic view.

Created by [Mohammed Kamareddine, MD](https://echosuite.app/about/) · [Sources & educational scope](https://echosuite.app/about/)

[Open this view in Probe Lab →](https://echosuite.app/#plax)

## Probe position

3rd-4th interspace, immediately left of the sternum

## Acquire the view

Place the patient left lateral, set the probe beside the sternum, and aim through the LV long axis.

## Optimize the image

Slide one interspace at a time and maximize LV length without showing papillary muscle.

## Practice in EchoSuite

The interactive lab pairs the probe and mannequin with the corresponding clinical reference cine. Enter Practice to move the probe and follow the view’s acquisition coaching.
