For patients with prosthetic heart valves, what premidication is recommended before dental procedures?

• A. Antibiotic prophylaxis for SBE
• B. No prophylaxis
• C. Vaccination
• D. Insulin

Answer: (A)

Bacteria can enter the bloodstream during dental work and can seed a prosthetic heart valve, potentially causing infective endocarditis. To prevent this, antibiotic prophylaxis before the procedure is recommended to reduce the bacterial load at the time of bacteremia. A standard approach is to give an appropriate antibiotic within about an hour before the dental procedure. If oral dosing isn’t possible or the patient has a penicillin allergy, suitable alternatives exist (such as a macrolide or clindamycin). Vaccination or insulin do not address this risk.
