Valvular Heart Disease Flashcards
Recognize etiologies of valvular heart disease (VHD).
Most common arise from; degenerative (senile calcification)
- Myxomatous degeneration (MVP)
- Congenital (bicuspid aortic valve)
Explain Grading Scale for murmurs
Barely audible
Faint, soft
Louder, easily heard
Very loud with palpable thrill (vibration)
Heard with stethoscope barely touching the chest with thrill
Can hear without stethoscope or can hear with stethoscope close to chest: palpable thrill
list the systolic murmurs
MR (Mitral Regurgitation) TR (Tricuspid Regurgitation) AS (Aortic Stenosis) PS (Pulmonic Stenosis) VSD (Ventricular Septal Defect) ASD (Atrial Septal Defect)
list the diastolic murmurs
AI or AR (Aortic insufficiency or regurgitation
PI or PR (Pul insufficiency or regurgitation
MS (mitral stenosis)
TS (Tricuspid stenosis
Atrial Myxoma
what are some causes of acute mitral regurgitation?
Acute
Ischemic papillary muscle dysfunction (CAD, MI, 2nd most common cause of MR)
Rupture chordal tendineae
Infective Endocarditis
Volume overload, inc. LA pressure, pul. Edema, RVF/LVF cardiogenic shock
what are some causes of chronic mitral regurgitation?
Chronic
MVP (Mitral valve prolapse) most common
Myxomatous or degeneration or MAC (mitral annular calcification)
what will you hear on PE in regards to mitral regurgitation?
PE
systolic murmur, blowing at apex, radiates into left axilla. Reduced S1 use diaphragm
what will you hear on PE in regards to mitral regurgitation?
PE
systolic murmur, blowing at apex, radiates into left axilla. Reduced S1 use diaphragm
What is Mitral Valve Prolapse (MVP)?
Mitral Valve Prolapse (MVP) one or both leaflets prolapse into left atrium
Female (7:1), redundant tissue with myxedematous degeneration
Asymptomatic to chest pain, SVT, PVCs, dyspnea, systolic murmur at apex, may have click/murmur increase with Valsalva and standing.
Murmur increase with dec vent volume and chamber size
Rx – reassure or if symptomatic give BB
what will you hear on PE in regards to tricuspid regurgitation?
Blowing, systolic murmur, 4th ICS LSB: increase on inspiration (Carvallo sign)
what will you hear on PE in regards to tricuspid regurgitation?
Blowing, systolic murmur, 4th ICS LSB: increase on inspiration (Carvallo sign)
Prominent V wave in jugular venous pulse is associated with what murmur?
tricuspid regurgitation
Prominent V wave in jugular venous pulse is associated with what murmur?
tricuspid regurgitation
what is the most common etiology of aortic stenosis?
Etiology: degenerative calcification most common
Biscuspid - AoV, RHD
What murmur results in pressure overload and LVH?
aortic stenosis
Pathology: PRESSURE OVERLOAD; LVH Sever AS, if AoV area < 1 sq. cm
