High Yield PTEeXAM Review Part 9 - 11 Flashcards
With CWD, how often are sound waves mitted and received?
Continuously
What is the shape of the normal tricuspid annulus?
Elliptical and Non-planar
The severity of functional TR is best determined by:
Tricuspid Annular Diameter
Which is the most sensitive echo sign of acute myocardial ischemia?
A. Decreased systolic wall thickening
B. Increased diastology wall thickness
C. Reduced endocardial excursion
D. Reduced epicardial excursion
E. Compensatory Hyperkinesis
A = Decreased Systolic Wall Thickening
Cleaning of TEE probes is performed by:
Gluteraldehyde Submersion
Increase in MPI (Myocardial Performance Index) from baseline implies what is occuring?
Worsening of systolic and diastolic dysfunction
Using the photo below, what is the formula for the myocardial performance index?
[A - B] / B
Is MPI (Myocardial Performance index) load dependent or independent?
Dependent
Whata is MPI in terms of:
IVCT
IVRT
ET
[IVRT + IVCT] / ET
What is a normal value of MPI?
< 0.35
What MPI would tell you that LV dysfunction exists?
>0.5
What is the formula for velocity of circumferential shortening?
FS / ET
What TV Valve Leaflets are seen in the modified bicaval view?
Near field = Posterior / Septal
Far field (Away from probe) = Anterior
