Valvular Heart Disease/Murmurs Flashcards
What are 3 etiologies of Valvular Heart Disease?
- Degenerative (senile calficiation)
- Myxomatous Degeneration
- Congenital
Murmurs result from?
Turbulence across a valve or increased blood flow
ex. anemia/pregnancy
Stenosis impedes?
Forward flow
What does stenosis lead to?
Pressure overload
=> Hypertrophy and heart failure
Regurgitation is?
Reversal of flow, leaky valves or fail to close
What does Regurgitation lead to?
Volume overload
=> Dilation
What are 6 Systolic murmurs (between S1 and S2)?
Mitral Regurgitation Tricuspid Regurgitation Aortic Stenosis Pulmonic Stenosis VSD ASD
What are 6 systolic murmurs?
Mitral and Tricuspid Regurgitation
Aortic and Pulmonic Stenosis
VSD and ASD
What are 4 Diastolic murmurs? (between S2 and S1)
