Слайд 3

Endocarditis is an inflammation of the inner layer of the

heart, the endocardium. It usually involves the heart valves .Other structures that may be involved include the interventricular septum, the chordae tendineae, the mural endocardium, or even on intracardiac devices. Endocarditis is characterized by a prototypic lesion.
Endocarditis is an inflammation

Слайд 4

There are multiple ways to classify endocarditis. The simplest classification

is based on etiology: either infective or non-infective, depending on whether a microorganism is the source of the inflammation or not.

There are multiple ways to classify endocarditis.

Слайд 5

Infective endocarditis
Since the valves of the heart do not receive

any dedicated blood supply, defensive immune mechanisms cannot directly reach the valves via the bloodstream.

Слайд 6

The endocarditis seen in acute rheumatic fever may set off

a more chronic process that can eventually produce heart valve damage. In other words, it can produce rheumatic heart disease.

Слайд 7

What is endocarditis
Infective endocarditis is an infection of the endocardial

surface of the heart, which may include one or more heart valves, the walls, or a septal defect.

Слайд 8

What are symptoms of endocarditis
Fever, skin hemorrhages especially under the

nails, blood in urine and blood in sputum.

Слайд 9

Fever, weakness, shortness of breath, loss of appetite, weight loss.

Signs include anemia, new or changing heart murmur, peripheral emboli and hematuria.

Слайд 10

Endocarditis develops in the endocardium
Endocarditis develops in the endocardium, the

inner tissue of the heart. It starts if this tissue has been damaged, injured, or infected. Much as a cut on the skin causes a scab to form, damage to the endocardium can lead to the formation of a blood and tissue clot.

Слайд 11

In infective endocarditis
In infective endocarditis, the clots are caused by

bacterial or fungal infection, inflaming and damaging the heart cells.

Слайд 12

Acute rheumatic endocarditis
This heart lesion was an autopsy finding in

a girl of 16 years.
There is a row of small, firm, grayish vegetations along the contact line of the mitral valve cusps.

Слайд 13

Endocarditis, myocarditis and pericarditis.
They are the cardinal feature of rheumatic endocarditis.

But endocarditis is just one component of the pancarditis that occurs in acute rheumatic fever, i.e. there are inflammatory changes in all three layers of the heart, endocarditis, myocarditis and pericarditis

Слайд 14

In infective endocarditis, the clots are caused by bacterial or

fungal infection, inflaming and damaging the heart cells. The infection reaches the heart through blood that's carrying a concentration of bacteria.
