Q

What is IVCT

A
  • the period from the av valve closure (end diastole) until SL valve open (beginning of systole)
  • volume is at its greatest
    -pressure rises rapidly in preparation of SL valve opening

Q

What is rapid ejection

A

22
Q

What is RV free wall strain

A
  • assesses rv systolic fxn
  • the change in length of the myocardial segment / the original length
23
Q

What is RV free wall strain calculation and NL value

A
  • Change in length / original length

24
Q

What are the 2 main pressures of the left heart

A

LVEDP: <15mmhg
Mean LAP: <10mmhg

25
What measurements do you take to assess diastology
- PW Doppler of MV - PW TDI lateral and septal MV annulus - PW Doppler RUPV - 2D LA volume - cw Doppler of peak TR
26
values for LA ESV bsa
16-34, 35-41, 42-48, >48
27
Normal values for septal e prime and lateral e prime
- septal e: >7cm/sec -lateral e: >10cm/sec
28
What is the E/e ratio?
The peak mv E wave velocity/septal and lateral e (avg)
29
What E/e ratio suggest normal LAP
E/e ratio < 8
30
What E/e ratio suggest elevated LAP
>14
31
What is the equation for RVSP
RVSP = 4(Vtr)^2 + RAP
32
What are the 4 values to grade tree A of diastology
1) averaged E/e ratio > 14 2) septal and lateral TDI; < 7cm/sec & <10cm/sec 3) TR velocity > 2.8 m/sec 4) LA Volume index > 34ml/m^2
33
What is the probability of diastolic dysfunction based off the 4 measurements in tree A
- Less than 2 = Normal DD - 2/4 = indeterminate - more than 2 = DD confirmed
34
What is DD grade if E/A is >2
- Elevated LAP - grade 3
35
What is DD grade if E/A is < .8
- Normal LAP - but grade 1 DD
