الإجابة: A. Oral clindamycin 1 hour before the procedure
A prosthetic valve + dental extraction is a high-risk indication for IE prophylaxis, given as a single dose 30–60 min before the procedure. Amoxicillin is first line, but with penicillin anaphylaxis the cohort review lists clindamycin (or azithromycin) instead. Amoxicillin is contraindicated here, and skipping prophylaxis is wrong for a prosthetic valve.

Amoxicillin is preferred only when there is no penicillin allergy; with penicillin allergy an alternative agent is used instead.

Prophylaxis is indicated: a prosthetic heart valve is a qualifying cardiac indication and a tooth extraction is a qualifying dental procedure.
