Cardiac PLAX

LVOT

LA

Aortic Root LV

MV

Descending Aorta

Purpose:

LV function, identify PCE

Probe:

Phased array

Preset:

Cardiac

Position:

Supine or left lat decub

Orientation:

Marker to R shoulder, 2nd ICS or patients cardiac window

Sono Landmarks:

Proximal LV, LVOT, MV

Area of interest:

1. Mitral valve (EPSS) 2. LV myocardial walls3. Relative RVOT : aortic root : LA4. 2D assessment of MV and AV

Images:

Aim to capture an image including MV, proximal LV (excluding apex), and AV

Interpretations:

Eye Ball of LV function. Good LVF: 1. EPSS < 0.8cm2. Myocardial excursion3. Myocardial thickening

Troubleshooting:

Upright positioning can be challenging. Consider supine and left lateral decubitus. If difficult windows explore area to find patient’s specific cardiac window

RVOT

Severe LV depression

Pericardial Effusion
