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)
Aortic Regurgitation
Pulmonic Regurgitation
Mitral Stenosis
Tricuspid Stenosis
What are 4 diastolic murmurs?
Aortic and Pulmonic Regurgitation
Mitral and Tricuspid Stenosis
Murmur grade 1
Barely audible
Murmur grade 2
Soft and faint
Murmur grade 3
Loud and easily heard
Murmur grade 4
Loud with a thrill (palpable vibration)
Murmur grade 5
Heard with stethoscope barely on chest and with a thrill (palpable vibration)
Murmur grade 6
Heard without stethoscope on chest and with a thrill (palpable vibration)
Mitral Regurgitation is associated with what?
Mitral Valve Prolapse
Attributes and symptoms of Mitral Regurgitation
- Blowing at apex and radiates to axilla
- Variable clinical presentation
Attributes and symptoms of Tricuspid Regurgitation
- Blowing at 4th ICS on left
- Increases on inspiration
- Prominent V wave in jugular venous pulse
- Asymptomatic
Attributes and symptoms of Aortic Stenosis
- Crescendo-Decrescendo and radiates to sternal notch/carotids
- Narrow pulse pressure
- Parvus (weak) and Tardus (late) pulses
- Dyspnea, syncope, angina
What will be seen on ECG with Aortic Stenosis if it causes LVH with strain?
Downsloping of ST segment
Pulmonic stenosis is associated with?
Tetralogy of Fallot
Attributes of Pulmonic Stenosis
- Crescendo-Decrescendo and radiates to left shoulder
VSD is a ____ murmur
Holosystolic
ASD involves?
Splitting of S2
Attributes and symptoms of Mitral Stenosis
- Low pitch (use bell), rumbling and followed by opening snap
- Dyspnea, orthopnea, palpitations and hoarseness
Attributes of Tricuspid Stenosis
- Increases with inspiration (carvallo sign)
- Prominent A wave in jugular vein
Attributes of Aortic Regurgitation
- Decrescendo and wide pulse pressure
- Demusset sign (head bobs with pulse)
- Quincke’s sign (capillary nail pulsations)
Acute and Chronic Aortic Regurgitation symptoms
Acute - pulmonary edema
Chronic - dyspnea, angina, orthopnea
Attributes of Pulmonic Regurgitation
- Decrescendo
- - Associated with pulmonary hypertension
Which valve murmurs are associated with the carvallo sign (increased with inspiration)?
Tricuspid
Decrescendo murmurs
Aortic and Pulmonic Insufficiency (regurgitation)
Crescendo-Decrescendo murmurs
Aortic and Pulmonic Stenosis
