3 types of rheumatic heart disorders
|
1. rheumatic fever
2. rheumatic heart disease 3. valvular heart disease |
|
rheumatic fever-most susceptible age and risk factors
|
ages 5-15 most susceptible
risks: environmental factors-crowded living conditions, poor sanitation, poverty, genetics, immunodeficiency |
|
What is RHD and when does it occur?
|
valvular dysfunction that occurs after acute or repeated attacks of RF
|
|
Rheumatic fever caused by?
when do symptoms occur? |
caused by abnormal immunologic response to strep A antigens, inflammatory response occurs.
symptoms occur 2-3 weeks after initial pharyngeal infection |
|
4 common manifestations of rheumatic fever
|
1. cardiac
2. musculoskeletal 3. skin 4. neurological |
|
cardiac signs of RF (3)
|
1. carditis (CP, heart murmur, pericardial friction rub)
*involves all layers of heart and valvular dmg occurs |
|
musculoskeletal signs of RF (1)
|
1. migratory polyarthritis (red, hot or swollen joints in knee/ankle/elbow/wrist)
*doesn't progress to chronic disease |
|
skin signs of RF (2)
|
1. erythema marginatum (temp non-itchy rash w/ pale center & red margin)
*on trunk and extremities 2. subcutaneous nodules (painless pea-sized palpable nodules of wrists/elbows/ankle/knee joints) |
|
neurologic signs of RF (1)
|
1. Sydenham's chorea (uncoordinated jerking movements affecting face/feet/hands)
|
|
lab tests run for RF (4)
|
1. elevated ESR
2. elevated c-reactive protein 3. titer 4. throat culture-positive for group A strep |
|
meds for RF (2)
|
1. antibiotics-penicillin #1, erythromycin #2
*finish all meds, diarrhea and nausea common 2. anti-inflammatory drugs *given for those patients w/ arthritis symptoms |
|
types of valve disease in adults (4)
|
1. mitral stenosis
2. mitral regurgitation 3. aortic stenosis 4. aortic regurgitation |
|
common causes of valvular heart disease (3)
|
1. degenerative disease (most common)
2. RHD 3. infective endocarditis |
|
4 charac of valve stenosis-what happens?
|
1. valve leaflets fuse together & can't fully open/close
2. orifice of the valve is narrowed & rigid 3. increases pump effort 4. increases afterload |
|
2 charac of regurgitation-what happens?
|
1. improper closing
2. blood refluxes back through the valve into area it just left |
|
3 disorders of mitral valve
|
1. mitral valve stenosis
2. mitral valve regurgitation 3. mitral valve prolapse |
|
charac of mitral valve stenosis-what happens? (4)
|
1. narrowed valve orifice
2. blood flow into LV impaired 3. increase LA workload 4. LA hypertrophy (dilates to accomadate higher blood volume b/c blood isn't getting thru to LV) *pressure overload |
|
manifestations of mitral valve stenosis (5)
|
1. DOE-blood can't get from lungs into heart & backs up into lungs
2. orthopnea 3. cough 4. paroxysmal nocturnal dyspnea 5. murmur |
|
charac of mitral regurgitation-what happens? (2)
|
1. backflow of blood into LA
2. LA dilation & hypertrophy *volume overload |
|
manifestations of mitral regurgitation (4)
|
1. DOE
2. orthopnea 3. pulmonary congestion 4. murmur |
|
charac of mitral valve prolapse
|
1. one of both mitral valve cusps billow into LA during ventricular systole
2. affects women more often 3. asymptomatic |
|
disorders of aortic valve (2)
|
1. aortic valve stenosis
2. aortic valve regurgitation |
|
charac of aortic stenosis (4)
|
1. narrowed valve orifice
2. blood flow impaired from LV into aorta 3. increase LV workload 4. LV hypertrophy (dilates) *pressure overload |
|
manifestations of aortic stenosis (3)
|
1. DOE
2. angina 3. murmur |
|
charac of aortic regurgitation (2)
|
1. backflow of blood into LV from aorta
2. LV dilation & hypertrophy |
|
manifestations of aortic regurgitation (2)
|
1. dyspnea
2. chest pain |
|
diseased heart valve summary (4)
|
1. stenosis & regurgitation
2. one problem may predominate 3. susceptible to infection 4. abnormal heart sounds |
|
treatments for valvular heart disease
|
1. percutaneous balloon valvuloplasty
2. valvuloplasty 3. open commissurotomy 4. annuloplasty 5. valve replacement |
