Measurements & Views

What do we look for w/ PLAX increased depth?

mass, pericardial effusion, and pleural effusion

What do we assess in PLAX?

Chamber size, wall thickness, global function, and valvular function

What do we rule out w/ PLAX?

Chamber dilation, hypertrophy, decreased function, WMA, and valvular abnormalities

AO Root is measured in?

Mid-systole, leading edge to leading edge

AO Root Measurement (F,M)

Female: 23 +-2mm, Male: 26+-3mm

PLAX Ascending AO is measured in?

End-Diastole

ASC AO Measurement (F,M)

PLAX LVOT zoom is measured how and where?

mid-systole, inner edge to inner edgeVOTL

LVOT normal range

18-22mmhyW

Why do we put color over valves in PLAX zoom?

To assess for valvular stenosis or regurgitation

Why do we put color on septum in PLAX?

Rule out abnormal flow such as a VSD (ventricular septal defect)

What do we do if VSD is found/

Assess with spectral doppler
