Chamber Quntification Flashcards
LV segments on A4C
Inferoseptal and anterolateral
LV segments on A2C
Inferior and Anterior
LV segments on PLAX
Anteroseptal and inferolateral
LV segments on PSAX
SALI
Causes of coronary sinus dilation
Increased RA pressure, persistent L SVC
RWT Equation
2PWT/LVIDd
Hypertrophy Square
Where to measure linear dimensions?
PLAX, perpendicular to long axis, level of MV tips
When to measure wall thickness
End diastole
LAD Segments
Anterior, anteroseptal, apex
RCA segments
Inferior, inferoseptal
LCx segments
+/- anterolateral
+/- inferolateral
MV on M mode
D: MV opens
E: Maximum opening in rapid filling
F: diastasis
A: atrial contraction
C: MV closure
SAM appearance on MMode
No flat systolic line (movement towards ventricular septum)
MVP on MMode
Systolic bowing greater than 3 mm below C-D line
MS on MMode
Reduced E-F slope (severe = flat). Loss of A wave possible
Myxoma on MMode
Opacification behind leaflet
AI on MMode
LV dilation, reverb against the MV leaflet (Austin Flint murmur)
AS on MMode
Thick cusp and reduced separation
Bicuspid AV on MMode
Eccentric closure line
Low SV on MMode
Tapering and early AV closure
HCM on MMode
Midsystolic closure and fluttering
PH on MMode
Flying W
PS on MMode
Early notch in waveform
