12: Valvular Heart Disease Flashcards
valvular heart disease arises mostly from what two causes?
- congenital
2. myxomatous degeneration
stenosis and regurgitation create pressure and volume overload - which creates which?
Stenosis -> pressure overload
Regurg -> volume overload
four main systolic vs four main diastolic murmurs
- Systolic: MR, TR, AS, PS
2. Diastolic: AR, PR, MS, TS
are VSD and ASD diastolic or systolic?
systolic
murmur grading scale from 1-6
- barely audible
- soft
- louder
- loud with thrill
- heard with stethoscope barely on chest
- heard without stethoscope
which sex is more likely to have MVP?
female
symptoms of MVP
asx or CP, SVT, PVCs, dyspnea
which valvular heart defect can be associated with TOF, PS, VSD, RVH, or overriding aorta?
pulmonic stenosis
what size mitral valve area becomes significant mitral stenosis?
1-1.5cm
four “signs” of Aortic Regurg + explain them
- DeMusset sign: head bob w/ beats
- Quincke’s sign: capillary nail pulsations
- Traube sign: pistol shot sound over femoral A
- Duroziez’s sign: diastolic murmur over femoral artery when compressed
murmur heard in pulmonary regurgitation
diastolic decrescendo murmur at 2nd ICS, increased S2
what condition is associated with pulmonary regurgitation?
pulmonary HTN
