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 |
