Which of the following is an example of a high-risk condition that necessitates infective endocarditis prophylaxis for dental procedures?

Infective endocarditis prophylaxis for dental procedures is reserved for patients with specific high‑risk heart conditions, especially when prosthetic material or devices are present in the heart or when certain congenital heart diseases are involved. The key idea is that bacteremia from dental work can seed abnormal endocardial surfaces, and prosthetic tissue or repaired defects create a higher risk nidus for infection. Repaired ASD without residual defects fits this pattern because closing the defect often uses a prosthetic patch or device that remains in the heart. Even if there’s no remaining shunt, the presence of that prosthetic material makes the patient fall into the high‑risk category where prophylaxis is considered appropriate for dental procedures. By comparison, a mild mitral valve prolapse with no regurgitation generally does not confer high risk, so prophylaxis isn’t routinely required. Repaired VSD with no residual defects likewise depends on specifics of the repair and timing; however, the classic textbook example emphasized here is the presence of prosthetic material from an ASD repair, which clearly aligns with the criterion for prophylaxis.
