C8: PSAX And Measurements Flashcards
What are the PSAX levels?
- PV/PA
- Base (AV level)
- MV level
- LV base level
- LV mid
- LV apex
Which levels do we use to assess wall motion?
LV base, mid and apex
Which level is the widest part of the LV?
LV base
Which leaflets are seen in the PSAX PA level?
L posterior pulmonary cusp
R posterior pulmonary cusp
Which leaflets of the TV do we see at the PSAX base (AV level)? And the PV?
Septal and anterior
L post and R post
Which way should the septum be bowing in the MV level view?
To the RV
When separating the MV leaflet into scallops, how would you number them?
From R of the screen to Left of the screen starting with A1/P1
Why don’t we look at wall motion at the MV lvl?
Because the annulus is stiff and LV wall thickening is non symmetrical at this level
What structures are we seeing at the PSAS LV base level/
The chordae and possibly floating pap muscles
At the PSAX mid level, how should the movement of the LV appear?
All ways moving at the same time
Is PSAX which side of the screen is medial and which is lateral?
R = lateral L = medial
Is which segments of the LV walls are the pap muscles often found?
The mid inferior wall and mid anterolateral wall
Which view in PSAX is good for viewing pericardial effusions?
PASX apical level
should not see pap muscles at this level
By assessing wall motion, can we directly or indirectly diagnose ischemia or infarct?
Indirect
Where would you perform an RVOT and PA diameter measurement? When would you do this?
RVOT: proximal to the PV
PA: distal to PV
Only if enlarged
