1

Cardiovascular Disorders - Endocarditis (Chapter 17)

What is endocarditis?

It is the inflammation of the endocardium.

2

Cardiovascular Disorders - Endocarditis (Chapter 17)

Who is at high risk for developing endocarditis?

Clients who have invasive procedures or devices (prosthetic heart valves) or IV drug users.

3

Cardiovascular Disorders - Endocarditis (Chapter 17)

What is the organism that causes acute endocarditis?

Staphylococcus aureus

4

Cardiovascular Disorders - Endocarditis (Chapter 17)

What is the organism that causes subacute endocarditis?

Streptococcus viridans

5

Cardiovascular Disorders - Endocarditis (Chapter 17)

Briefly explain the pathophysiology of endocarditis.

Organisms in the bloodstream attach to the endocardial lining of the heard and become enmeshed in deposits of fibrin and platelets. These vegetations develop on the heart valve leaflets, eventually scarring and deforming the valves. The scarring impairs the valves from normal closing, causing regurgitation of blood through the valve. The normal flow of blood through the heart chambers is affected and heart murmurs develop.

6

Cardiovascular Disorders - Endocarditis (Chapter 17)

What are the manifestations and complications of infective endocarditis?

Elevated temperature (>101.5ºF). Cough. SOB. and complaints of joint pain. Heart murmurs are common.

Complications include heart failure and infarctions of other organs (lungs, brain, kidneys, or bowel) from embolization of vegetative fragments.

7

Cardiovascular Disorders - Endocarditis (Chapter 17)

What are the peripheral manifestations of endocarditis?

Petichia (on the trunk, conjunctiva, and mucous membranes)
Splinter hemorrhages (small painful growth on fingers and toes)
Small purplish-red lesions on the palms of the hands and soles of the feet.

8

Cardiovascular Disorders - Endocarditis (Chapter 17)

What is the interdisciplinary care for endocarditis?

Prevention of infective endocarditis is key (Educate and Teach)
Prophylactic antibiotics (prior to high-risk procedures)
IV antibiotics (because of the protective fibrin over the vegetation)

9

Cardiovascular Disorders - Endocarditis (Chapter 17)

What is the indication for surgery with endocarditis?

To repair or replace damaged valves. The most common indication for surgery is valvular regurgitation that causes heart failure.

10

Cardiovascular Disorders - Endocarditis (Chapter 17)

What is the priority nursing care of the client with infective endocarditis?

Effectively treating the infectious process, maintaining heart function, and preventing complications.

11

Medical Surgical Nursing Care Text Book - Chapter 17

The nurse caring for a client with bacterial endocarditis knows that this disease

A. Generally is mild and self-limiting
B. Affects the muscle layer of the heart
C. Often leads to end-stage heart failure requiring cardiac transplant.
D. Usually affects clients with previous heart or valve damage.

D. Usually affects clients with previous heart or valve damage.

Rationale:
Bacterial endocarditis occurs most frequently in clients who have had previous heart or valve damage that affects the flow of blood through the heart. The innermost layer of the heart is affected, and treatment is necessary to reduce the risk of permanent heart valve damage.
