Q

What is the calculation for CSA

A

d2X.785

17
Q

What are the values for RV and RF%?

A

1+ Mild = ≤ 20cc ( < 20%)
2+ Mild to Moderate = 20-40cc (20 -40%)
3+ Moderate = 40-60cc (40-50%)
4+ Severe = ≥ 60cc ( > 50%)

RF% is same scale, but in percentages

18
Q

How do you calculate SV?

A

determine CSA of valve and multiply by VTI of flow.

19
Q

How do you calculate RF%?

A

Divide the Regurgitant Volume by the Stroke Volume

20

What is the longitudinal dimension of the RV?

A

no greater than 8.6cm

23
Q

What is the normal range of decel for the TV?

A

120-200ms

24
Q

What is the dimension of the RVOT at the valve?

A

no greater than 2.7cm

25
Q

What is the normal range of TDI for the right heart?

A

<10cm/s is abnormal

10-19cm/s is normal

26
Q

What are the normal values of RV EF%

A

NL= 44-71%

< 44% is abnormal

27
Q

What is the normal area for the RA?

A

13.5 cm2

28
Q

What are area ranges for the TR Jet?

A

10cm2 = Severe

29
Q

What are the grades for TR Vena Contracta?

A

7mm = Severe

30
Q

What are the grades for TR Jet Radius?

A

< 5mm = mild
6-9mm = moderate
>9mm = severe

31
Q

What are the grades for TRA/RAA?

A

34% = severe

32
Q

what do you know about dP/dT?

A

Right side:
1200/ dt
< 400mmHg is abnormal

33
Q

What are the values for TAPSE?

A 
NL = 16-30mm
AbnL = <16mm
34
Q

What are the 2 classifications of Tricuspid Regurgitation? Give and example of each.

A

Functional
(secondary to other etiology)
dilated TV annulus
PHTN

Anatomical
Tricuspid Atresia
Ebstein's Anomaly 
SBE/Perforation
Tricuspid prolapse
35
Q

List the Vena Contracta and Pisa Radius ranges for TR

A

PISA
< 5mm = Mild
6-9mm= Moderate
>9mm = Severe

Vena Contracta
< 7mm = Mild
> 7mm = Severe

36
Q

What structure is continuous with the RA and can dilate with TR? What is the Nl size?

A

Coronary Sinus

≤ 5mm

37
Q

How do you calculate RV in TR?

A

SV (tv) - SV (rvot) = RV (tr)

38
Q

How do you calculate SV for the TV?

A

CSA of TV x TV max VTI = SV(tv)

39
Q

Describe diastology for Right Heart filling pattern.

A

E/A = < 0.8 suggests impaired relaxation
E/A = 0.8-2.1 and E/e’ < 6 and predominant diastolid hepatic flow suggests Pseudonormal filling pattern.
E/A >2.1 and Decel <120ms suggests restrictive filling.
