Rheumatic heart disease
what valve does Acute rheumatic endocarditis affect?
mitral valve
- Carditis
- Migratory polyarthritis, no
- Subcutaneous nodules
- Erythema marginatum
- Rheumatic chorea (Sydenham’s chorea)
Major Jones Criteria
•History, Symptoms, Labs.
•REMEMBER: in acute Rheumatic disease leads to mitral
regurgitation but chronic leads to stenosis
Minor Jones Criteria
- Virus (Coxsacki B) is the Most Common Cause
- Pathology: interstitial edema with lymphocytes
- Complication: congestive cardiomyopathy
Myocarditis
• It is a myocardial dysfunction, Most Common Cause is
unknown
Cardiomyopathy
Mainly systolic dysfunction
•Causes: idiopathic, alcoholism, myocarditis or drugs (adriamycin)
Congestive (dilated) cardiomyopathy
- very young age
- congenital (AD)
- diastolic disorder
- asymptomatic
- causes sudden death in athletic person
Hpertrophic cardiomyopathy
mainly diastolic dysfunction, due to hemochromatosis
⇑ iron), amyloidosis(⇑ pre-albumin
Restrictive cardiomyopathy
Friable, embolic vegetation
Bacterial Endocarditis
acute bacterial endocarditis (ABE):
Staph. Aureus
subacute Bacterial Endocarditis (SBE):
strept. Viridans
Associated with SLE, mainly affects mitral & tricuspid
valves
Libman Sacks endocarditis (non bacterial endocarditis)
non-bacterial thrombotic (NBTE), associated with tumors
& DIC due to much mucin secretion which affects the blood coagulation.
