Tricuspid Stenosis Flashcards
What are the CAUSES of TS?
- rheumatic
- carcinoid
- right atrial or TV mass
- congential
What is the most COMMON CAUSE of TS?
rheumatic heart disease
What is CARCINOID?
when someone has cancer that metastasis to liver
What occurs when someone has CARCINOID?
liver releases serotonin to the right heart causing shortened, fixed tricuspid leaflets
What are the SIGNS & SYMPTOMS of TS?
- signs of overload to vena cava
-jugular venous distention
- peripheral edema
- hepatomegaly
What type of AUSCULTATIONs are heard in TS?
- diastolic rumble at LLSB
- opening snap
How do we DIFFERENTIATE auscultation of TS from MS?
diastolic rumble may accentuate with inspiration
What are the TREATMENTS for TS?
- commissurotomy (balloon or surgical)
- valve replacement
- medication management
Who are prone to endocarditis?
IV drug users
What are 2D FINDINGS of TS?
- thickened restricted leaflets & shortened chordae
- diastolic doming of TVL due to commissural fusion
- RAE
- dilated IVC
- small protected RV
What are the M MODE FINDINGS of TS?
- decreased E to F slope, anterior motion of posterior (or septal) leaflet, decreased D to E, decreased or absent a wave
What are the COLOR/DOPPLER findings of TS?
- candle flame jet
- velocity > .7m/sec
- prolonged slope w/ longer PHT (doppler envelope)
- increased atrial reversal wave on PW of HV
Why is there an increased atrial reversal wave of HV?
because not as much volume can go through RA so it moves back into HV
What ways do we QUANTIFY TS?
- MPG
- TVA via PHT
- TVA via Continuity Equation
What does it mean if theres TS regarding other valves?
TS never an isolated lesion, must evaluate other valves especially MV
