valvular heart diseases Flashcards
what kind of murmur is MS
low pitched diastolic rumble
cause of MS
rheumatic fever
MAC
MV atresia
secondary to a mass
prosthetic valve
radiation
chain reaction due to MS
1.increase LA pressure
2. MV leaflet doming
3. LAE
4. back up into the pulmonary veins
signs and symptoms of MS
- dyspnea
- RHF
- dizziness
- chest pain
- murmur
- SOB
- swollen feet/legs
what do you see on echo with MS
doming of the leaflets
MS thickening
decreased MV area
anterior motion of the MV
LAE
m mode of MS
absent A wave
decreased amplitude of E wave
decreased e-f slope
chronic MS with pulmonary hypertension on echo
increased right sided pressure causing septum flattening
parallel wall motion
small d shaped left ventricle in systole and diastole
m mode of the PV with pulmonary hypertension
“flying w”
mild MS area
> 1.5
severe MS area
<1.0
Mild MS PHT
90-150
severe MS PHT
> 220
severe mean PG MS
> 10
MVA area equation using PHT
220/PHT
what 3 ways can MVA be aquired
PHT
deceleration time
