Antibiotic Prophylaxis After CABG for Dental Procedures

High-Risk Cardiac Conditions Requiring Prophylaxis

• The American College of Cardiology and the American Heart Association recommend antibiotic prophylaxis for patients with prosthetic cardiac valves, including transcatheter-implanted prostheses and homografts, before dental procedures involving manipulation of gingival tissue, periapical region of teeth, or perforation of oral mucosa 1, 2
• The American College of Cardiology recommends antibiotic prophylaxis for patients with prosthetic material used for cardiac valve repair, previous infective endocarditis, unrepaired cyanotic congenital heart disease, or repaired congenital heart disease with residual shunts/valvular regurgitation at or adjacent to prosthetic material, before dental procedures involving manipulation of gingival tissue, periapical region of teeth, or perforation of oral mucosa 1, 2, 4

Rationale for Current Recommendations

• A history of CABG alone is not considered a high-risk condition requiring prophylaxis, according to the American College of Cardiology and the American Heart Association 1, 2

Recommended Prophylactic Regimens

• The American College of Cardiology recommends a standard regimen of Amoxicillin 2g orally 1 hour before procedure for patients with high-risk conditions, and Clindamycin 600mg orally 1 hour before procedure for penicillin-allergic patients 3
• For penicillin-allergic patients without a history of anaphylaxis, angioedema, or urticaria, the American Heart Association recommends Cephalexin 2g orally as an alternative 4, 3

Dental Procedures Requiring Prophylaxis

• The European Society of Cardiology and the American College of Cardiology recommend prophylaxis for dental procedures involving manipulation of gingival tissue, periapical region of teeth, or perforation of oral mucosa in high-risk patients 6, 2

Important Considerations

• The American College of Cardiology and the American Heart Association emphasize that maintenance of optimal oral health is more important than antibiotic prophylaxis for reducing infective endocarditis risk 5, 3
• The American College of Cardiology recommends that potential sources of dental sepsis should be eliminated at least 2 weeks before implantation of a prosthetic valve or other intracardiac/intravascular foreign material 6, 3

Common Pitfalls to Avoid

• The American College of Cardiology advises against prescribing antibiotics for CABG patients without other high-risk conditions, and against administering prophylaxis for non-dental procedures in the absence of active infection 1, 2
• The American Heart Association recommends using appropriate antibiotic regimens and timing, and emphasizes the importance of regular dental care and good oral hygiene 4, 3, 5, 3
