Valvular heart disease board review Flashcards
4stages of VHD
A at risk
B progressive
C. severe asx c1 compensated LV or RV C2 deccomistated LV or RV
d. Severe sx
CHF AHA stages of HF
NYHA classes /CCS
A. at risk
B. asx with chf
C. sx
D. refractory
I. asx
II. Mild limitations - >1 flight, > 2 blocks
III. mod limitations - 1 flight of stairs or 2 blocks
IIII.Severe limitations - at rest, limited activity
Frequecny of echo follow up for VHD
Stage B 3-5 years Stage C 6 mo to 1 year.
STS risk given high risk
> 8%
How many frailty on katz make someone high risk
What about prohibitive risk
2 or more
> 50% n1 year predicted risk of death
AVA index associated with severe
< 0.6
SV index for low flow
< 35 ml/M2
What can mask a high gradient with AS
HTN (need to control bp) needs to be less than 140 for accurate assessment
TAVR vs SAVR GL recs based on risk
Low risk SAVR Class I
Intermediate risk SAVR Class I , TAVR IIa
High risk SAVR or TAVR class I
Prohibitive risk TAVR class I
How to decided TAVR vs. SAVR for intermiediate risk
Class I SAVR and Class IIa TAVR, Need heart team decision
AI surgical replacement
severe at and sx or asx and severe LV dilation SVESD > 50 mm / 25 indexed or LVEDD > 65 (note for MR its only 40 mm ESD)
in asx pt with AI do you give someone a ACEor ARB
No need unless htn or sx with severe dz
problem with BB and AR
longer diasotolic interval with slower HR and then get more AR. (slow stenotic lesions and keep regurgitant lesions fast.)
What size ventrical can you replace the AV in an asx individual; with severe AR
- 5 cm EsD or 25 cm indexed , 65 EDD
- what is the most common fusion for BAV
- this leads to dilatation
Second most common type of BAV?
right and left
of the tubular portion bc jet blows ant and to the right
right and non cusps (this is assocaiated with a higher location of the aortaopthy tubular to arch)
