TR Quiz Flashcards
How do you calculate FAC
Fractional Area Change:
EDA-ESA/EDA = FAC
What are the values of FAC?
NL: 35-60% Abnormal <35% Mild: 25-35% Moderate: 18-24% Severe 17
How do you calculate MPAP?
80 - ( 0.5 x rvot accel time )
How do you calculate PAEDP?
4 x (PR end diastolic velocity2) + RAP
simple bernoulli using PI jet vel. and RAP
How do you calculate PVR?
TR peak vel./ rvot VTI X 10 + 0.16
What are the ranges of PA Pressures?
PA Pressures NL: 18-25mmHg Mild: 30-40mmHg Moderate: 40-60mmHG Severe: ≥ 60mmHg
How is the RVOT area useful to know?
RV Stroke Volume can be determined
SV = rvot VTI x rvot Area
What do PA acceleration times indicate?
They are inversely related to pressure.
acceleration time decreased = pressure increased
What are normal acceleration times for PA waveforms?
NL ≥ 140ms
Abnl < 140ms
< 90-70ms indicates PA pressures 70mmHg and above.
Which TV Leaflets do you see in the TTE Views
RA/RV: Posterior Leaflet + Anterior Leaflet
SAX/base: Septal Leaflet + Anterior Leaflet
Apical 4 Chmbr: Septal + Anterior
SubCostal SAX: Septal + Anterior
What are patient symptoms of TV disease?
fatigue poor appetite vomitting tender liver heart racing
What are some physical findings of TV disease?
distended neck veins RVE dilated PA enlarged liver peripheral edema -pitting edema -ascites poor appetite jaundice
What is the normal range for MPAP?
NL= 9-18mmHg
What is the normal range for PAEDP?
NL= 4-12mmHg
What is the calculation for RSVP
TR Pressure Gradient + RAP
What is the calculation for CSA
d2X.785
What are the values for RV and RF%?
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
How do you calculate SV?
determine CSA of valve and multiply by VTI of flow.
How do you calculate RF%?
Divide the Regurgitant Volume by the Stroke Volume
What is the dimension of the TV annulus?
no greater than 4.2cm
What is the dimension of the mid RV chamber?
no greater than 3.5cm
What is the longitudinal dimension of the RV?
no greater than 8.6cm
What is the normal range of decel for the TV?
120-200ms
What is the dimension of the RVOT at the valve?
no greater than 2.7cm
What is the normal range of TDI for the right heart?
<10cm/s is abnormal
10-19cm/s is normal
What are the normal values of RV EF%
NL= 44-71%
< 44% is abnormal
What is the normal area for the RA?
13.5 cm2
What are area ranges for the TR Jet?
10cm2 = Severe
What are the grades for TR Vena Contracta?
7mm = Severe
What are the grades for TR Jet Radius?
< 5mm = mild
6-9mm = moderate
>9mm = severe
What are the grades for TRA/RAA?
34% = severe
what do you know about dP/dT?
Right side:
1200/ dt
< 400mmHg is abnormal
What are the values for TAPSE?
NL = 16-30mm AbnL = <16mm
What are the 2 classifications of Tricuspid Regurgitation? Give and example of each.
Functional
(secondary to other etiology)
dilated TV annulus
PHTN
Anatomical Tricuspid Atresia Ebstein's Anomaly SBE/Perforation Tricuspid prolapse
List the Vena Contracta and Pisa Radius ranges for TR
PISA
< 5mm = Mild
6-9mm= Moderate
>9mm = Severe
Vena Contracta
< 7mm = Mild
> 7mm = Severe
What structure is continuous with the RA and can dilate with TR? What is the Nl size?
Coronary Sinus
≤ 5mm
How do you calculate RV in TR?
SV (tv) - SV (rvot) = RV (tr)
How do you calculate SV for the TV?
CSA of TV x TV max VTI = SV(tv)
Describe diastology for Right Heart filling pattern.
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.
