This document discusses infective endocarditis in children. It defines infective endocarditis as a microbial infection of the heart valves or inner lining of the heart. Infective endocarditis can be acute or subacute based on clinical course. Common causative organisms include Staphylococcus aureus, Streptococcus species, and fungi. The document outlines signs, symptoms, investigations, treatment, and antibiotic prophylaxis recommendations for different types of cardiac conditions and medical/dental procedures.

2. Infective Endocarditis:
Definitions
• A microbial infection of a cardiac valve or the endocardium caused by
bacteria, fungi, chlamydia or viral
Categorized as acute or subacute based on the rapidity of the clinical
course
3. Subtypes
1-Acute Bacterial Endocarditis (ABE)
Fulminant and severe course
Death is Frequent
Organisms: Staphylococcus aureus, Streptococcus pyogenes,
Streptococcus pneumoniae
2- Subacute Bacterial Endocarditis (SBE)
Indolent, slower and less severe course over months
Organisms: Streptococcus viridans
9. Janeway lesions
Non-tender, small erythematous
or hemorrhagic macules or
nodules in the palms or soles,
The pathology is due to a type
III hypersensitivity reaction.
16. Investigation
1- Blood culture
For aerobic/anaerobic /fungus
positive for SIE :Viridans streptococci, for acute IE Staphylococcus aureus
involvement
2-Echocardiogram positive for IE
3 - other blood test: CRP, CBC
4- other systems (might be affected)
brain (embolization/mycotic aneurysm) : brain MRI, brain MRA
kidney functions
abdominal U/S
chest CT
..
17. Specific
AB : IV for at least 2
weeks
Prophylaxis
Treatment of complication
Non specific
general: antipyretic
Hospitalization
Treatment
18. Prophylaxis
Bacteremia resulting from daily
activities is much more likely to
cause IE than bacteremia
associated with a dental
procedure.
1- Maintenance of optimal oral
health and hygiene may reduce the
incidence of bacteremia from daily
activities and is more important than
prophylactic antibiotics for a dental
procedure to reduce the risk of IE.
19. 2- Antibiotic prophylaxis is no longer
recommended for any other form of
CHD, except for the conditions ???

20. The antibiotic prophylactic regimens recommended by the AHA are only
for patients with underlying cardiac conditions associated with the
highest risk of adverse outcome
from infective endocarditis.
Antibiotic prophylaxis is indicated for the
following high-risk cardiac conditions:.
Feb 5, 2018
21. Cardiac Conditions for which IE Prophylaxis
Recommended for Dental Procedures (4)
1- Previous Infective Endocarditis
2-Prosthetic Cardiac Valve
3- Certain Congenital Heart
Disease (CHD)
4. Cardiac transplant
22. Cardiac Conditions for which IE Prophylaxis
Recommended for Dental Procedures
3- Congenital Heart Disease (CHD)
- Unrepaired Cyanotic CHD
- Completely Repaired CHD with Prosthetic
Material or Device, during the first 6 months
after the procedure
- Repaired CHD with Residual Defects at the
Site or Adjacent to the Site of a Prosthetic
Patch or Prosthetic Device (which Inhibit
Endothelialization)
4- Cardiac Transplant Recipients who Develop
Valvulopathy (valve disease)
23. Infectious Bacterial Endocarditis
Prophylaxis No Longer Recommended
for the Following Conditions
Acyanotic HD
Ventricular Septal Defect
Ostium Primum Atrial Septal Defect
Pulmonary Stenosis
Aortic Stenosis/Insufficiency
Mitral Valve Prolapse with Valve Regurgitation
Patent Ductus Arteriosus
Coarctation of Aorta
Rheumatic Heart Disease
Hypertrophic Cardiomyopathy
Wilson W, Taubert KA, Gerwitz M, et al. Circulation. 2007;115.
24. NOT Recommended:
“Probably Innocent Murmur” never evaluated
by cardiologist but getting SBE prophylaxis “just in case.”
Recommended for
1- invasive dental procedures
2-invasive respiratory
procedures
3- invasive skin procedures
Endocarditis Prophylaxis
25. Dental Procedures for Which
Endocarditis Prophylaxis Is
Reasonable for Patients
All dental procedures that involve
1- manipulation of gingival tissue or
2- the periapical region of teeth or
3-perforation of the oral mucosa**
26. Dental Procedures for which Endocarditis
Prophylaxis IS NOT Recommended in Patients
with the Highest Risk Cardiac Conditions
Routine anesthetic injections through non-infected tissue
Taking dental radiographs
Placement of removable prosthodontic or orthodontic appliances
Adjustment of orthodontic appliances
Placement of orthodontic brackets
Shedding of deciduous teeth
Bleeding from trauma to the lips or oral mucosa
27. Other than dental procedures
1- ear piercing
2- skin tattoo
3-tonsillectomy, adenoidectomy
3- incision or biopsy of the respiratory mucosa (eg, tonsillectomy, adenoidectomy). Antibiotic prophylaxis
is not recommended for bronchoscopy unless the procedure involves incision of the respiratory tract mucosa
4- Patients with high cardiac risk who undergo a surgical procedure that involves infected skin, skin
structure, or musculoskeletal tissue should receive an agent active against staphylococci and beta-
hemolytic streptococci (eg, antistaphylococcal penicillin, cephalosporin)
