Which medical condition requires antibiotic prophylaxis due to prosthetic material used for cardiac valve repair?

• A. Immunosuppressed patients
• B. Arteriovenous hemodialysis shunts
• C. Neurosurgical shunts (type dependent)
• D. Prosthetic material used for cardiac valve repair

Answer: (D)

The key idea is that prosthetic material in the heart provides a surface for bacteria to cling to if bacteria enter the bloodstream, making infective endocarditis more likely. Because of this, prophylactic antibiotics are indicated to protect someone with prosthetic material used for cardiac valve repair from bacteremia-triggered infection during procedures that can introduce bacteria. The other options involve other devices or conditions, but they do not inherently carry the same established need for antibiotic prophylaxis for endocarditis related to cardiac prosthetic material.
