Latest Guidelines for Infective Endocarditis Prophylaxis

Antibiotic prophylaxis for infective endocarditis should only be given to the highest-risk cardiac patients undergoing dental procedures that manipulate gingival tissue or perforate oral mucosa—prophylaxis is NOT recommended for gastrointestinal, genitourinary, or respiratory procedures. 1

Highest-Risk Patients Who Qualify for Prophylaxis

Prophylaxis is reasonable only for patients with cardiac conditions associated with the highest risk of adverse outcomes (not just increased lifetime risk) from infective endocarditis 1:

  • Prosthetic cardiac valves or prosthetic material used for valve repair 1
  • Previous history of infective endocarditis 1
  • Congenital heart disease (CHD): Complex cyanotic CHD and post-operative palliative shunts, conduits, or prostheses 1
    • After surgical CHD repair with no residual defects, prophylaxis is recommended only for the first 6 months until endothelialization occurs 1
  • Cardiac transplant recipients who develop cardiac valvulopathy 1

Prophylaxis is NOT recommended for other valve conditions including mitral valve prolapse, bicuspid aortic valve, calcific aortic stenosis, or any other native valve disease 1.

Dental Procedures Requiring Prophylaxis

Prophylaxis should only be considered for dental procedures involving 1:

  • Manipulation of gingival or periapical region of teeth
  • Perforation of oral mucosa (including scaling and root canal procedures)

Prophylaxis is NOT needed for 1:

  • Local anesthetic injections in non-infected tissue
  • Treatment of superficial caries
  • Removal of sutures
  • Dental X-rays
  • Placement or adjustment of removable prosthodontic or orthodontic appliances
  • Shedding of deciduous teeth
  • Trauma to lips and oral mucosa

Dental Implants

The indication for dental implants in at-risk patients should be discussed case-by-case, with patients informed of uncertainties and need for close follow-up 1.

Antibiotic Regimens for Dental Procedures

Standard regimen 1:

  • Amoxicillin 2 g orally (adults) or 50 mg/kg orally (children), given 30-60 minutes before the procedure

If unable to take oral medication 1:

  • Ampicillin 2 g IV/IM (adults) or 50 mg/kg IV/IM (children)
  • OR Cefazolin or ceftriaxone 1 g IV/IM (adults) or 50 mg/kg IV/IM (children)

For penicillin allergy 1:

  • Clindamycin 600 mg orally or IV (adults) or 20 mg/kg (children)
  • OR Azithromycin or clarithromycin 500 mg orally (adults) or 15 mg/kg (children)
  • OR Cephalexin 2 g orally (adults) or 50 mg/kg (children)

Critical caveat: Cephalosporins should NOT be used in patients with history of anaphylaxis, angioedema, or urticaria with penicillin due to cross-sensitivity 1.

Fluoroquinolones and glycopeptides are NOT recommended due to unclear efficacy and potential for inducing resistance 1.

Non-Dental Procedures: Prophylaxis NOT Recommended

Gastrointestinal and Genitourinary Procedures

Prophylaxis is NOT recommended for 1, 2:

  • Gastroscopy, colonoscopy, esophagogastroduodenoscopy
  • Cystoscopy
  • Vaginal or caesarean delivery
  • Transesophageal echocardiography

Exception: In high-risk patients with active GI or GU tract infection, antibiotic therapy is reasonable to prevent wound infection or sepsis (not for endocarditis prophylaxis) 1. For high-risk patients undergoing elective cystoscopy with enterococcal urinary tract infection or colonization, antibiotic therapy to eradicate enterococci before the procedure is reasonable 1.

Respiratory Tract Procedures

Prophylaxis is NOT recommended for 1:

  • Bronchoscopy or laryngoscopy
  • Transnasal or endotracheal intubation

Exception: If a high-risk patient undergoes an invasive respiratory procedure to treat an established infection (e.g., drainage of abscess), an antibiotic regimen containing an anti-staphylococcal drug should be given 1.

Skin and Soft Tissue Procedures

Prophylaxis is NOT recommended for any dermatological or musculoskeletal procedure 1.

Rationale for Restrictive Guidelines

The dramatic shift toward more restrictive prophylaxis recommendations is based on 1:

  • Infective endocarditis is more likely from daily activities (tooth brushing, flossing, chewing) causing random bacteremias than from medical/dental procedures 1
  • Prophylaxis may prevent an exceedingly small number of cases (if any) 1
  • Risk of antibiotic-associated adverse effects exceeds the benefit from prophylactic therapy 1
  • Optimal oral hygiene is more important than prophylactic antibiotics for reducing endocarditis risk 1

Pre-Surgical Dental Clearance

Potential sources of dental sepsis should be eliminated at least 2 weeks before implantation of a prosthetic valve or other intracardiac/intravascular foreign material, unless the cardiac procedure is urgent 1.

Important Clinical Pitfalls

  • Do not give prophylaxis based solely on increased lifetime risk of endocarditis—only give it based on risk of adverse outcomes if endocarditis develops 1
  • Do not continue outdated practices of giving prophylaxis for GI/GU procedures, as this represents a Class III recommendation (should not be done) 1
  • Maintain strict adherence to care bundles for central and peripheral catheters, with systematic replacement of peripheral catheters every 3-4 days 1
  • Limit use of infusion catheters and invasive procedures when possible, favoring peripheral over central catheters 1
