1- Multiple blood culture


2- Echocardiogram

Respiration with murmurs

Left sided increase with expiration


Right side increase with inhalation

Location of thrombi on heart valves sterile vs infectious

Sterile- inferior


Infectious - Superior

Rheumatic fever

1- Caused by group A beta hemolytic streptococcus


2- Can progress to rheumatic heart disease


3- Affect high pressure balances Mitral > Aortic > Tricuspid


4- Early- mitral regurgitation late- mitral stenosis


5- Type 2 hypersensitivity

Associations of rheumatic fever

1- Aschoff bodies - granuloma with giant cells


2- Anitscjkow cell - enlarge macrophages with oval wavy nucleus


3- Anti- streptolycin O titer and Anti DNAse B titer

Symptoms of rheumatic fever

1- Migratory Poly arthritis


2- Carditis - myocardial


3- Subcutaneous nodules


4- Erythema marginatum


5- Syndenam chorea

Diagnosis of rheumatic fever

Clinical 1- Fever


2- Arthritis


Laboratory 1- Prolonged PR interval


2- Increase ESR or CRP


Criteria 1- Positive culture for group A beta hemolytic streptococcus or positive ASO antibody


And


2- 2 major or 1 major and 2 minor


Treatment of rheumatic fever

Penicillin G

Pathogenesis of rheumatic fever

Molecular mimicry


M protein produce by group A strep can cross react and bind to the heart


Cross react with myosin

Virulent factors if rheumatic fever

1- Streptoycin O - 1- lyses


2- Test ASO antibody titer


2- Streptokinase- Coat Bacteria


3- Hyalauranidase- Break apart connective tissue e


4- DNAse

Molecular mimicry In rheumatic fever

1- Against M protein/myosin- myocarditis


2- Against GAGs- valvular damage


3- Against gangliosides in the brain - chorea

Erythema marginatum

An evanescence rash with ring margin

Syphilitic heart disease

1- Tertiary syphilis disrupts the vasa vasorum of aorta (obliterative endarteritis) cause atrophy of vessel wall and dilatation of aorta and valvular ring


2- Can cause calcification of aortic root, ascending aorta arch and thoracic aorta


3- Tree-bark appearance (due to fibrosis)


4- Can cause aneurysm of ascending aorta, aortic arch and aortic regurgitation

Acute pericarditis

1- Inflammation of the pericardium


2- Symptoms - pleuritic chest pain worst in inspiration and lying flat relive with sitting up and leaning forward


3- Complicated by pericardial effusion/cardiac Tamponade


4- Signs 1- Pericardial rub


2- ECG widespread ST elevation and PR depression


5- Cause 1- Idiopathy


2- Infection (coxsachie virus)


3- Autoimmune (SLE)


4- Uremia


5- Cardiovascular (post MI- Dressler syndrome)


6- Treatment - NSAID, Colchicine, glucocorticoids, dialysis (uremia)

Myocarditis

1- Inflammation of the myocardium


2- Common cause of SCD in patients <40


3- Symptoms- chest pain, SOB, arrhythmia, fever (persistent tachycardia without fever is characteristic)

Causes of myocarditis

1- Viral (Adenivirus, coxsackie B, parvovirus B19, HIV, HHV-6, lymphocytic infiltrate with focal necrosis)


2- Parasites (Trypanosoma cruzi, Toxoplasmosis)


3- Bacteria (Borrelia burg for feri, mycoplasma pneumonia, corynebacterium diphtheria)


4- Toxins (Carbon monoxide, Black widow venom)


5- Rheumatic Fever


6- Drugs (Doxorubicin, cocain)


7- Autoimmune (Kawasaki disease, sarcoidosis,SLE, Poly myositis/Dermatomyositis)

Complication of myocarditis

1- Sudden cardiac death


2- Arrhythmia


3- Heart block


4- Dilated cardiomyopathy


5- Heart failure


6- Mural thrombosis with systemic emboli

What histologic finding is suggestive of myocarditis

Lymphocytic infiltrate with focal necrosis of myocardial tissues

Cardiac tumors

1- Most common heart time is metastasis (eg melanoma )

Myxomas

1- Most common primary cardiac tumor in adults


2- 90% develop in the atrium (left atrium)


3- Associated with a ball valve obstruction with multiple episodes of syncope


4- IL- 6 causes constitutional symptoms (fever, night sweat and weight loss)


5- Early diastolic (tumor plop) sound


6- Histology gelatinous material


7- Immerse in glycosaminoglycans

Rhabdomyomas

1- Most common primary cardiac tumor in children


2 Associated with tuberous sclerosis


3- Histology Harmartomastis growth

Kussmaul sign

1- Increase JVP during inspiration instead of normal decrease


2 Inspiration- negative intrathoracic pressure not transmitted to the heart- Reduce right ventricular filling- back up of blood in vena cava- increase JVP


3- Causes 1- Constructive pericarditis


2- Massive pulmonary embolus


3- Restrictive cardiomyopathy


4- Right sided hear failure


5- Right atrial or ventricular failure

Hereditary hemorrhagic telangiectasia

1- Also called osler-Weber-rendu syndrome


2- Autosomal dominant disorder of blood vessels


3- Findings 1- Blanching lesions of the skin and mucus membrane


2- Skin discoloration


3- Recurrent epistaxis


4- Hematuria


5- GI bleeding


6- AV malformation
