According to the AHA guidelines, which patients should receive antibiotic prophylaxis for dental procedures?

• A. Patients with prosthetic heart valves or repair material, patients with a prior history of infective endocarditis, patients with certain congenital heart defects, and heart transplant recipients with valvular disease.
• B. Only patients with prosthetic heart valves
• C. Only patients with prior endocarditis and congenital defects
• D. All patients undergoing dental procedures

Answer: (A)

Identifying which heart patients are at high risk for endocarditis and would benefit from antibiotic prophylaxis before dental work. Bacteria entering the bloodstream during dental procedures can seed abnormal or prosthetic cardiac tissue, so prophylaxis is reserved for those with conditions that put them at greatest risk for serious infection. According to the guidelines, prophylaxis is recommended for: patients with prosthetic heart valves or repair material; patients with a prior history of infective endocarditis; certain congenital heart defects (such as unrepaired cyanotic defects, repaired defects with residual issues at the site or near a prosthetic device, and repaired defects with prosthetic material within the first six months after the procedure); and heart transplant recipients who have valvular disease. This targeted approach aims to prevent endocarditis in those most vulnerable, rather than giving antibiotics to everyone undergoing dental procedures. Other options either miss important high-risk groups or inappropriately extend protection to all patients. For example, limiting prophylaxis to only prosthetic valves excludes other high-risk categories, while advising prophylaxis for all dental patients would unnecessarily expose people to antibiotics and their risks.
